Hello all,
So quite some time ago i inherited my grandfathers 17.5" Hydra-sport VS 120 bass boat before he passed and this boat has a lot of sentimental value, He was my bass tournament partner whom i miss dearly. Now the motor is an 88 Evinrude 100 XP which ran great before now. So yesterday me and a buddy of mine went on a fishing trip and we ran into a problem a couple hours in and far from the ramp. I was running the boat about 70% of WOT and it bogged down and stalled hard. I've always ran the motor a little richer than 50:1 do to the age. I would rather deal with fowled plugs and know the motors internals are getting what it needs. Now being the person I am, I'm always prepared for worst case scenario and had my tool bag! Which became a real blessing yesterday and got us home safely! After the motor stalled i tried restarting it and it would hesitate to start, spit and sputter and finally bog out again. So i raised the motor and pulled the plugs to see if maybe they have fowled. This is were i found a serious issue, on the 3rd plug i pulled i actually found that the gap on the plug was smashed completely shut... Talk about an "oh F$%^" moment... So i opened the gap back up the best i could and put the plug back in. Sure enough the motor fires up and doesn't stall, sputter or bog. Talk about a tough motor!!. But anyways it was enough to get the boat to plain and keep a good slow steady pace, running maybe 20% of WOT back to the ramp. and we made it! Talk about being relieved!! What a day that was and a nightmare it could've been.. Sorry for the rant for those who may not be interested but i figured the scenario would help understand the problem a little better. My guess is that a rod bearing went out causing the piston to smack the plug shut at higher RPMs. Maybe i'm wrong?.. Now i can't afford to just go out and buy a new motor for this boat and call it a day.. wish i could!. Maybe an old used one if the price is right but from what i can tell, it's still a pretty penny for a 100hp old and used! I've rebuilt old chevy motors and currently rebuilding a hemi motor, but a boat motor would be an all new playing field. Especially a 2 stroke motor.. Would i be in over my head trying to rebuild this motor? and be better off trying to replace the power head? Which may be an option. Any suggestions and opinions would be great!
