Cheep repower

I have a '91 Yamaha 150 that runs like a 15 year old engine. No real problems but has its quirks.

I have a connection to a boatyard that did a repower for a guy. He had twin 2001 Yamaha 150's and somehow the port engine ingested salt water. They want to get rid of the old engines and controls as a set for $2300. Engines have 500 hrs.

Do you think I should try to get only the starboard engine? Offer 12 or 15 & see what happens?

Is there any hope for the port engine? Could it be rebuilt? Sell it to MJ?

This would be a big project for me. I can build a house from the ground up but have never changed an engine.

Thanks,

2ndFiddle,

I'm no mechanic and I'm fairly new to boating, but I would buy both of those engines.  Even the engine that took in salt water can still be useful as a parts motor later down the road if you should ever need them.  Or, as you said, you could take your time with it and rebuild it.  Or, you could simply remove the good parts and put them up for sale on Ebay.  Either way, $2300 just for the good engine seems like a good deal to me, especially with the controls.  

And as far as removal and installation of an outboard, it's a piece of cake. I was able to do it with no prior experience. So, if I could do it, you certainly can. ;)
 
grace is right. if i came across a deal like that i would be all over it. yammy's are great motors. only prob i know of is that parts for them are real high. so having a parts motor not a bad idea. with that said, parting out on ebay should bring in quiet a few duckies, if you choose to go that route. tilt and trim alone should bring you 5-6 benjamins!
 
Keep in mind one of those engines is probably counter-rotating... ;) ...but even this is not reason for passin' off a good deal, just be aware of it as a possibility so you can work w/ it... ;D ...
 
I asked the manager to feel the guy out and see if he would part with one engine if he won't I will grab the whole package.

The props are gone so I don't know which is the counter rotating engine. How does that work? Is there a differential that switches the rotation? If I needed to could I switch parts with the other engine?

I asked the same question and they did not have an answer. The mechanic said they diagnosed the problem and sugested the solution of repower and the owner agreeed. They never asked the guy what he did. The yard was just happy to have a guy who would buy two new Yamaha's without batting an eye.

if you can get the non counter motor and use the other for parts you will be set for life!!

I have also heard (i think here) that you can a counter rotating motor for a main motor??
 
MJ is right.  There's not much difference between the counter rotating motors and the others.  I think Skools or somebody else gave a good explanation somewhere on the forum.  I had asked the very same question some time ago.  I was pursuaded enough to buy the engine I now have for my V which is a counter rotating motor.  
 
seems to me if one was pickled the other is also...i'd have to hear that puppy run...if it does thats a steal.
 
Fiddle, hear it run, have a compression check done, it would be hard to dunk one engine and not it's twin, unless the block cracked or a head gasket type of thing.
 
I belive one motor is good one bad!!

What makes you guys not belive that?? That is why a lot of guys have twins, just incase one craps out you have the other!

Maybe the one wasn't getting oil or something, in this case a gasket might have gone??

Just have it checked out from a good mariner and see, I bet you will be fine and have all the parts you ever want!

If I had the money I be looking at a deal like that!

MJ, one motor is bad due to salt water intrusion. How does one get saltwater in it and not the other when they were mounted as twins on the same boat? There may be a reasonable explanation but I'd be careful. Maybe it "almost" sank and had a serious list to one side???
 
Well they are mine now. Had to match the price the wholesaler was giving $2500. I hope that it lasts as long as my '91.

I will keep everyone posted when I start the work. I know that I will have many questions.

I may also sell my "91 150 and possibly parts from the spare.
