Hello everyone, im new here and somewhat new to boats as a whole. It came to my attention today that I have a bad piston on number three cylinder. ( 1986 Evinrude 140 ) Something went through the intake side and beat the crap out of the piston, bad enough that theres only about half the piston remaining. My mechanic says theres a score on the cylinder wall and that it should be bored. My question is how long do you guys think I will make it if I dont bore it out but replace the piston and rings. Yes I understand that a score in the cylinder wall is a bad thing. But im hoping to get some use out of the boat while I either one, buy a new boat, two, re-power it, or save the money for a rebuilt motor. Im not stranger to turning wrenches, and I can get the parts needed for a relatively decent price, but cant afford a full rebuild right now. Ive been quoted 2-3000 for a rebuild from my mechanic if he does the work, and yes that includes parts. Im very confident that I could do the work myself but the score in the cylinder wall, which doesnt seem to be very bad, still has me a little on the edge of the port side, hahahahahaha. Thanks to all for your advice!!!!
