Evinrude 1987 140 v4 Rebuild

[THEFERMANATOR]

That pitting around the sleeves on #1 and #3 can cause head gaskets to blow out like no tommorrow. When I say decked I prefer the method where they use the big sheet of sandpaper on a granite top. This way you only take off what is needed, most of the time it's less than .002 thousandths to clean one up this way. And the V-4 loopers have REALLY high compression to begin with, roughly 140-145 on a good healthy one. Mine pops off at 155 and it is a B!TCH to start up, it takes 2 good batteries to kick it over with 2 guage battery cables. But it will SCREAM on the top end. Like I said earlier though, the carbs will drive you nuts most likely. Most everybody I've talked to has had problems after building one of these V-4 loopers and had to re-jet the carbs to fatten em up on the main and intermediate, but lean it out at idle.
