Hey Everyone,
NOT SO QUICK OF A QUESTION and sorry but I figure it would be better to provide as much info as necessary to get an accurate answer.
I am new to the boat world. I have a 1991 Mercury Force 150 on a old 91 cobra bass boat (bairly used, still in good shape other than seats) The motor has very low hours and I am supprised by how decent shape this boat is in for its age.
On to my Outboard. My mechanic said the motor has good compression in all cylinders but one, he said it would not be worth the money to pull the top end and repair. Sorry wish I had the results of the compression test to share. He did do a scope inspection of cylinders as well, and said they all look amazing, they show little to no scaring, wear, or carbon deposits, within any of the cylinders.
Mechanic said these are the needs or repairs of the motor he recomends:
Carb rebuild cost with parts etc., $300
Seals need replacement, $300 includes seals, lower end water pump, and lower end fluid.
Prop (chuncked up by me, but it did not cause any lower end damage per mechanic) Roughly $100 - $200 as seen on IBOATS.
Trim Tilt Relay Motor goes up, but will not lower???? Cost I think roughly 12 - 20 bucks after shipping.
And finally there is an issue with the hydrolic tilt - trim, not sure if there is an air bubble in the line, or if its low on hydrolic fluid, or if there is an actual leak (because I do not see signs of a leak and have not pulled the drain plug yet to inspect the issue), but with the motor trimmed up 3/4 way in reverse at very low speeds to back off trailer or to pull boat away from beaching it, will slam the motor to full lower possition which is why I chunked up my prop last time I had it out? I will push my boat off from beaching before I put it in reverse, but even then it will slam down with no resistence on the boat itself. Cost of repair unknown right now till I pull plug and cycle out old hydro fluid hell if there is any, and add new fluid etc. (Mechanic said if after doing all that, and it appears to be the hydrolics it is definately not worth the the money to repair, just run it as is and be careful, not even sure thats quality advise!)
Anyway - Looking at about $1000 bucks (minus repairs to hydrolic motor).
So question are the repairs worth it.
My mechanic said this and I quote, "these motors are hit or miss, you could spend the money on repairs and wind up with a dead motor in less than a few months, parts are getting to be nearly impossible to find, and costly, OR and a BIG OR (seeing as how the cylinders look good other than the one compression cylinder), you could make repairs and if you have luck on your side these motors "SOME OF THEM" will run like a sewing machine and last for quite a while enough to get your money out of it, and seeing as how the boat was for free" you wind up on top!
He personally said if it was his, he would probably do a carb rebuild, and seals/lower unit water pump? But even that would be questionable? And he would probably run it till it just died swapping out lower end fluid every once in a while! To me that seems a bit exagerated but he also has whatever boat he wants and I ONLY HAVE THIS ONE!
Should I repair or should I not! I fish tournaments as a co-angler, and really want to get out on the lake w/ my own boat, at least just for practice, I fish from shore now, unless I go out w/ friends, and I am tired of it! Would love to fix the boat, but want to know if the repairs seem worth the trouble.
Please any advise would be great! Thank you for your time!
