So yesterday I took an ol' high school buddy fishing in bodega bay for lings and salmon.normally I'd be a little apprehensive going that far in great white territory but He had friends in a buddy boat. So off we go. We cruised about 20,22 mph on flat seas. Beautiful. My little sea explorer was holding her own against the 25' bay runner.. Made our first drift, fish on a green ling. Fired the yami to get to the start of the drift again and smoke everywhere running like crap. Long story short we headed for home on the kicker a 2.5 hp Nissan for 30 miles. OMG 8 hours but we made it on 5 gas fill ups for the Nissan. I hadn't even started that little gem in 3 years but it sure saved my bacon yesterday. On the long ride home I found my top 2 spark plugs have water in them? Tried turning it over with plugs out to no avail. Anybody had similar problems with their Yamaha 85 hp ?

Wow!

My CV85 I bought new in 1983ish ran perfectly for me until I repowered with my Etec in 2012.
In fact....I sold it for $1600 to a guy living in Friday Harbor, WA and he's still using it...says he got a steal on the deal!!

Sorry to hear yours blew on ya. No telling when that kind of thing is going to happen.
From your description it sounds like you cracked the Powerhead allowing water into the cylinders.

Double Wow!!

Glad the kicker came through for ya.

Never stranded 30 mi out, but let down 1 too many times...next things you know you got brand new power on the back...

pretty sure it was worth the peace of mind as the buddy boat was rarely there for us...but boy does that price tag sting....

BestBoats · « **Reply #4 on:** August 30, 2016, 06:35:04 AM »

That's a long boring slog! Too bad the buddy boat didn't have a tow rope!

Wiliey,
My two cents just in case your interested :two cents:

I often fish off shore and I never turn my motor off when I am that far from shore. I find it is much better to just let the motor run. Less chance of the motor not starting.

Also in regards to your kicker. I no longer have a kicker but when I did when I launch my boat I always start my kicker and let it warm up. If I was to ever need my kicker I want to know it is going to run and most of all I want to know it is going to start up right away when I do need it. Just never know.

Tj805 · « **Reply #6 on:** August 30, 2016, 02:23:51 PM »

That's to bad about your main motor.
I have basically the same motor and it's been good for me.
Although my local mechanic said its a ticking timebomb.
And my theory is when it breaks it breaks.
That's what the kickers for

Wiley · « **Reply #7 on:** August 30, 2016, 04:02:41 PM »

Yup.. Had tow rope but probably couldn't go much faster than that anyway. So why mess up their fishing time? And yup I usually leave it running too, but not this time as we were trying to talk over 2 outboards. My mistake... I will employ the start the kicker at the dock advice though. Thanks for that one.. Brilliant. Unfortunately I may be dead in the water for quite awhile if my motor is toast. Have been pricing new ones and holy cow their a lot of money... Would probably need to finance for 30 years, so let's see new 90 etch at $11,700 installed for 30 at who knows what % equals anybody got an old surf casting pole for cheap???

Yachter Yat · « **Reply #8 on:** August 30, 2016, 05:15:35 PM »

Wiley:

Let me ask you this: At any time, while offshore, did you happen to be running the kicker in reverse, and backing down with the main engine shut off? You did say you usually keep your motor running, "but not this time as we were trying to talk over two outboards". If so, it might be possible that water was forced up into the power head. This happened to a friend of mine, years ago, while anchored from the stern in the Merrimack River. (A dumb thing to do, I know) When he went to start the motor, all you could hear was a "click". He pulled the plugs and turned the motor over a few times to see water spurting out from the cylinders. Believe it or not, after reinstalling the plugs that motor started. It was an Evinrude 4 cyl. two stroke.

$11,700?

You can get a 4 stroke Merc of Suzuki 90 for $2 grand less than that.

They keep telling me to buy it.

Salmon King · « **Reply #11 on:** August 30, 2016, 06:22:13 PM »

That's overpriced for that 90 Etec.
They are great motors but let's not get crazy spending that much.
TW IS RIGHT...SAVE 2k and get a Suzi!

Wiley · « **Reply #12 on:** August 30, 2016, 06:56:25 PM »

Update: $2500. Quote for repair = pulled head, new gaskets, exhaust burned through plates to cyl.? = water intrusion? 6 bolts helicoil.. Or new Yamaha 90 for $8500. Plus tax and install labor, about $9500. Ouch

La-Z-Buoy · « **Reply #13 on:** August 30, 2016, 07:28:10 PM »

I know you'd feel good with a new motor, aside from the price, but look for a decent used 4 stroke. They do show up and can be a more fiscally reasonable alternative. I picked up a nice Honda 90 several years ago and it was running like new when I sold the boat this year.

Threeweight · « **Reply #14 on:** August 30, 2016, 11:11:48 PM »

Put $2500 in that old motor, and you will have a nice running motor worth $2000, until the next thing breaks.

If you can afford it, repower. Either with a used 4 stroke, or with a new one.

Wiley · « **Reply #15 on:** August 31, 2016, 10:13:27 AM »

Yes and put $10k into a motor on a 1996 boat and I'll have a boat and motor worth $9k ???

Threeweight · « **Reply #16 on:** August 31, 2016, 10:58:03 AM »

I sold my 1989 Chaser for over $16k. A boat is always a depreciating asset, but a modern 4 stroke holds its resale value pretty darn well.

Repowered my old trophy (paid $6500 for it) with a $8500 Yamaha four stroke motor repower. Sold the set for $14,500 not bad considering I used the Yamaha for almost 10 years . Long term the repower should work out ok.

Yachter Yat · « **Reply #18 on:** August 31, 2016, 03:14:32 PM »

Resale value notwithstanding; if you plan on keeping that boat for a while, I'd seriously consider repowering with new. I'm sure nobody has to tell you (given you're recent experience) that it's a big ocean out there. For me, the peace of mind alone is well worth it. Think safety and stay safe. My 2.

Salmon King · « **Reply #19 on:** August 31, 2016, 06:41:30 PM »

Wiley,

A while back I posted a for sale post on several used 4-stroke motes I found on CL.
The guy runs a shop in Concrete, WA.
His motors come with a warranty (although that may not be of much use to you, it may provide some peace of mind).

I just seen he placed some new ads on the Skagit CL last night.

You gotta do what you can do but...
New or used I have to agree with everyone else here, your old 2-stroke is not worth the money to repair it.

:twocents:
S.K.

Wiley · « **Reply #20 on:** August 31, 2016, 07:45:23 PM »

Interesting, very interesting. With the four strokes weighing in at #100 lbs. more than my 2 stroke I've been thinking more along the lines of saving the $10k and the #100 lbs and investing in a 10 ish hp kicker at around a #100 lbs. and four times the speed of my 2.5 Nissan LOL. And definitely now a bay and delta boat. Really don't need to run 30 miles from launch offshore anyway. ??? :shrug9:

Come on Wiley, you're really not living up to the expectations of the Arima forum here. We're seriously trying to help you spend YOUR money

That would be pretty hefty for a Sea Explorer, wouldn't it?

Salmon King · « **Reply #24 on:** August 31, 2016, 08:59:20 PM »

well he was talking about an 85 so I thought I was in the ballpark.

Threeweight · « **Reply #25 on:** August 31, 2016, 10:04:53 PM »

Yamaha F70 is a 250# motor... probably about the same weight or even a little lighter than your old motor, and is just about ideal on the 16' Arimas. :twocents:

If you do decide to rebuild, I would absolutely hang a kicker on the boat if you take it that far offshore.

Wiley · « **Reply #26 on:** September 02, 2016, 06:16:47 AM »

Like the specs of that f70 Threeweight. Had been looking at the 90 but gph and weight of f70 very intriguing. Could be a rare case of bigger not necessarily better??? :arms:

Tj805 · « **Reply #27 on:** September 02, 2016, 06:59:08 AM »

They weight difference between a new Yamaha 90 and 115 is ten pounds
No one in there right mind is going to notice that little amount of weight.
I would go with the 115 if you could find a good deal on one.

Wiley · « **Reply #28 on:** September 02, 2016, 07:19:27 AM »

F70 vs. f90 = around a #100 lb. difference though. Then I could add the kicker and come in at about the same weight.

J Chaser · « **Reply #29 on:** September 02, 2016, 08:33:06 AM »

Have a close look at the F70. I have nearly 400 hours on mine in 3 years. It's a beautiful little motor.

I have a 4 stroke kicker, 2 batteries and a 27 US gallon tank in the stern, and it's fine.

There's a LOT to be said for keeping the stern light! Improved performance, better hole shot, improved mileage, more transom up against the waves, easier to beach, and etc.

Wiley · « **Reply #31 on:** September 02, 2016, 10:13:03 AM »

That's what I'm thinking J Chaser, how's the hole shot and top speed, gph etc. on an actual Arima hull??? I have the same 27 gal. Tank, 2 batteries, etc.
Beautiful picture of your stomping grounds.

J Chaser · « **Reply #32 on:** September 02, 2016, 10:35:52 AM »

Everything is great. I cruise at 24-26 mph. Top speed 31 mph.

Great hole shot. I have a Solas Amita 4 blade aluminum 13 pitch prop. I have my Lowrance hooked up for GPH but honestly I haven't checked it. It is really good on fuel, especially under 5000 RPM. It has a 6300 redline. I also have a 3 blade Yamaha 13 pitch for heavier trips. Too much prop for light loads and I reach the rev limiter, but it jumps right out of the water...

So you have a sea explorer or a 16'er. Some of your coharts that way have gone Tohatsu. I would look into them. I am hearing good things about them. And yes Markshorline makes the best point of all about stern weight. I completely agree, especially with that model in Arima's line up. Keep it light and factor in the kicker as you mentioned. You are on the right track.

I would explore all options on motors. Definitely factor in the duration you plan to own it. That model is a bit harder to sell vs the 17'er and getting some of your money out of a new repower in the short term will be difficult imho. Good luck.
