Any experiences with outboard motor rebuilds, good or bad? My starboard motor(1989 Johnson 150 vro) has low compression on 1 cylinder, 75lbs. and scoring on cylinder wall. This motor has 640hrs, rebuild or total repower? The port motor is in good shape.

homey- I bought my J225hp a few years ago with a "rebuilt" powerhead at a claimed 150 hours. Well, I've put over 700 hrs on the engine. Another 7 hrs this past Sat and Sunday. It's a 1989, same as yours. .03 rebuild it. David

If the motor still looks good and does not have much corrosion on it then go for it. If it looks like it will make it another 5-10 years I would not hesitate to rebuild it.

Sometimes the rebuilds are better than new motors which is what I have found out on my 21' Outrage. My 225hp Evinrude ran rougher before it was rebuilt and is much smoother now. I just always accepted it ran a certain way since I bought the motor new. Since it has been rebuilt is starts easier many times are the first key turn and idles much better. The whole motor runs smoother.

Rebuilding is a great way to go just be sure that you have a reputable mechanic do the work and make sure they achine everything to ensure sug fits. Have seen many back yard rebuilds go great and just as many go sour due to cutting corners on costs. Proper planning prevents poor performance. Whenyou are rebuilding something I always take the approach if you are not 100% sold on it holding up for a trip to portugal rebuild or replace it. That way when you are 100+ miles offshore and it breaks you aren't beating yourself up and most likely you won't be out there stuck to begin with.

with the price of 2 stroke outboard right now, you can repower with two new Johnson 150 2 strokes for 13 to 14 grand for two of them. You will not lose all of this money you will get alot back in resale!

Just my $.02 but a brand new outboard motor is about the fastest depreciating retail item that I have ever seen.

True, but in a couple years when DFI and four strokes rules, the value of a boat with shot engines will be nothing because it will cost so darn much to repower them!

I have a 1988 Johnson 200 rebuilt with 200 hours on it .03. I bought it at 250hours from a guy. I put 150 hours on this summer and in runs great.

Thank you, I really appreciate all the advice. The motors look great, little corrosion and fresh paint goes along way. I checked with a local outboard mechanic today, who quoted a ballpark figure of $3800-$4200, vro pump included and 1 year warranty. I'm still looking around and will get quotes in writting. I would like to get atleast 5 years out of them.

To repower with the Suzuki twin 140 4-strokes, I'm looking at approx. $18,000. Decisions, Decisions....Rebuild is looking good....

It sure makes a difference who does the work. I watched a local mechanic install head bolts with an air wrench! These must be torqued with a calibrated torque wrench. He rebuilds a lot of OMC motors, and is about $1000 cheaper than the competition on the sale of a rebuilt motor. Problem is, they don't last, and the word is getting around. None of the local commercials use him, even though he is from that crowd.

If only one cylinder is bad you can bore only one cylinder and install a new piston. That's what my Mercury factory repair manual says. I doubt a Johnson is any different. I say do it yourself for about 500 bucks. 2 stroke engines are really very simple. If it doesn't work then drop the $4500. If you're willing to spend $4500 then why not try the $500 fix. You'll learn something at a minimuum.

phatwhaler out.

phatwhaler, I considered boring the 1 cylinder but, a mechanic friend told me it wouldn't be balanced. The time it takes to bore out 1 cylinder, everyone seems to recommend doing the entire block. I'll look into it, and check with other mechanics. Thanks.

You may not have to bore it. You may get away with a hone job. You can also bore it then sleeve it so the piston remains stock size. $4k is WAY too high. You can get a rebuilt block with warranty for under $2k and you just swap your electronics, carbs, etc. I can get new Zuki 140's(4s) for $7k, why would you spend $4k on a 14 year old smoker?

Bigshot good point on purchasing a rebuilt head I too agree that the cost of repair quoted was way high. The local guys up by me said he never rebuilds anymore and now just buys reman powerheads for 2 reasons. 1) by the time he is done with machine shop parts and then tags on his labor bill he is almost twice the cost of buying reman pwerhead. 2) The shops that rebuild the powerheads on a regular basis are able to offer a warranty and extended warranty for 2 times sometimes 3 times the length that he can offer to his customers. Making not only the initial purchase cheaper but any problems down the road that may incur to be covered under warranty and most often the rebuilder simply supplies a new powerhead again for no charge. just my .02 as well.

its a gamble, you can rebuilt the powerheads and two weeks later the lower unit goes!

I can get new ones for that. Those are 2 strokes.

That's the ask, not the bid.

I'd offer him $8k for the package. Nobody (retail) up here in MA wants that inventory over the Winter.

ewalsh, I'll call the guy tommorrow and get the story on those motors. Thanks for the info....

Those are great engines and VERY torquy for 4cyls. $8-9k would be a good deal with controls,etc. Motors are bulletproof. they are a bit heavy at like 380 an engine.

Those Suzuki 140's are not counter rotating...

Don't think any 4cyl is CR for that matter. hydraulic steering is all you need....oops Yamaha 130's are CR.
