First off, I have an 86 15'6" fiberglass Stryker bass boat with a '87 evinrude 60hp on it. My dad bought the boat band new. It has been setting up for about 5 years. The floor has some soft spots so i'll have to replace it. i know the carbs will have to be cleaned/rebuilt. I engaged the throttle and turned the prob by hand and hear a loud squeaking sound about half way up  between the foot and the block.  Sounds like rubber. I guess there is a rubber seal that the shaft goes through? I know nothing about the internals. trim  motor also not working. worked fine last time the boat was used. could just be a switch, the trim motor was fairly new. I'll have to put a volt meter on that. Thanks for any help you can give me. I'm trying to find a reputable boat mech to take it to. just curious bout that sound!!!!                  

Where has this thing been stored?  It sounds like a whole lotta work for an old boat that is quite possibly all rotted out with a bunch of broken stuff on it.  

Things that will have to be looked at

Gas tank, if its metal it's probably rusted.

Batteries.

Steering system is probably shot.

Electrical, the same.

Trailer bearings.

If the floor has a bunch of soft spots I'm betting your transom is probably rotted too along with a bunch of saturated, moldy foam flotation in the hull.

Trailer electrical wiring is probably shot.

Tires are probably rotted.

Condition of bunks and trailer frame.

Carp 7, It sounds like you described my boat  

It's been outside, I am pretty sure the steering system is fine, it turns and stuff fine, I just put the cable on it last time i fixed it up.bout 4 years ago, only used it once cause of money at the time. it does need a little wiring redone that i know of. I do plan to buy a newer pretty nice boat in a couple years. My dad bought this boat new and he's gone now. So I dont wanna get rid of it so I figured I might as well fix it up and use it till i get some land paid off in a couple years then buy a newer one. transom is solid as can be, two little soft spots in the floor, decks solid as can be, gel coat is peeling off like crazy cause the guy that redone it bout 8 years ago done it wrong. $800 wasted for a year of looking good before peeling. I think I can get it fishable for bout $500 bucks probably unless the sound I hear is something major.

If $800 was all that was spent of a re-gel job, a year is about right.  Most professional jobs meant to last will cost you in the thousands, not hundreds.  Even those won't go much longer than 5 years before the inevitable happens.  

Good luck with the boat.  Something just sitting around outside for that length of time is never good.  Remember to maintain reality,  I know the boat has sentimental value but even your Dad would tell you to have a reasonable price in your head to spend fixing it and if it's more than that, walk away from it.
