    Starter Help!!!!

    Put a new perm magnet starter in my 2.5L 120hp last fall and only used it 3 times since. The stater seems to start out ok and then it will grind, like it is not engaging fully onto the flywheel. It also sometimes runs on with the key off for a couple of moments, usually only after it starts to...

    lifter replacement

    I am having the head gone over on my 1978 2.5L mercruiser(chevy) and decided to replace the lifters while I was at it. The pushrods and rocker arms looked good. My question is can I just replace the lifters and not the rest of the drivetrain if it looks good? I ask this because I have heard...

    Gaskets?

    I am replaced all the gaskets on my exuast/intake manifold as they are in bad shape. My concern is do I just put the gaskets in and tighten them down or use some sort of sealer between each gasket? (2.5L - 120hp).

    circuit breaker? fuse?

    Couldn't I just run a 50 or 60 amp fuse instead of a circuit breaker. It seems it would be just as effective protecting the motor, just would need to carry extra fuses.

    roller rockers

    I noticed some hi-power rebuilds of these 2.5L 4cyl. use roller rockers. Where can I get some that will work on my stock 2.5L(1978). I also need a set of pushrods and lifters. Could I just use the lifters and pushrods for a car application which used the 2.5L in 1978??

    marine grade

    Instead of buying really expensive marine grade plywood couldn't I just by a good sheet of hardwood and put some type of water seal on it? I am just making a deck up front for a bass style seat on an old tri-hull, it don't have to last but maybe 5 years or so. I can get a sheet a good sheet of...

    Tabs??

    I have searched the forums about trim tabs and hydrofoils and have come to conclusion from everyone's response that trim tabs are the way to go. I have a 78 tri-hull Imperial that needs a little help planning more efficiently because of a sorta weak 120 2.5L. My top speed with current prop is...

    12 vs. 24V

    I can't decide if I want a 12V 55lb or a 24V 65lb trolling motor for my boat. The ones I am looking at are MinnKota Power Drives. My boat is pretty heavy as it is an old 1978 Imperial 16ft with an inboard. I converted the bow to a bass style deck for fishing and am probably looking at the 54inch...

    rings or head?

    I have an older 2.5L and my compression is 125-130 in all but the number 4 cylinder which is reading 95. How would I test to see if it is the valves or rings?? Would a leakdown test tell the tale? Also, is 125-130 ok for compression readings? The boat runs decent, but won't idle really smoothly...

    12V.....24V??

    I want to mount a trolling motor on my 78 16ft tri-hull which I have converted the front to a floor with a swivel seat(bass boat style).

    Someone please educate me

    I am not very familiar with the differnces of a Tri-Hull boat and a V-boat. I am wondering what the pros and cons are of each and why tri-hulls aren't even made that I know of anymore? I would guess the V-hull has more advantages that is why they seem like the only one made anymore. I figure...

    What are TR/TRS outdrives? I seen a trim sender for a TR/TRS outdrive and wonder if it will work on my mercruiser outdrive. My outdrive is a 1978 but I'm not exactly sure what it is. I believe it is an alpha 1?

    I am considering repowering my boat next spring and going from the 2.5/120hp to the 3.0/140hp motor. I can have my 2.5L rebuilt for about 1200 bucks or I can get a new 3.0 for about 1800 bucks. Has anyone done this? Wondering if there will be enough differnce in power to justify spending the...
