I keep hearing OMCs and 25 hours for 3 Holers?
Tim:
I have a new 3 Holer OMC 49 cubic inch replacement complete block with innards and all that I bought with an entire blown up short shaft fishing engine at a neighborhood garage sale a little over a year ago now. I have been reluctant to tear it down just to put some other aftermarket pistons in it as opposed to keeping the new factory pistons in it now. I keep hearing this OMC 25 hour life span rumor stuff of some kind tossed around that such a new engine will last until what starts happening? Irregular wear, bore goes out, pistons wear out?? I am new to OMC 3 Holers specifically after being tortured by 3 Holer Mercs and Mariners that really jaded me and these 3 Holer 49 inch OMCs are sure no Merc so they all must have some stories and pointers to go with them all their own I know little or nothing about. Want to share????? Everyone???
Electric Fuel Pump with a Holley regulator??
Tim: I take it that 2 OMC fuel pumps looping through the 3 carbs is playing it fail "safer" than any single pump. I have some experience with Holley 12 volt pumps and fuel pump pressure regulators as well as Dupree 12 volt pulse pumps too from playing with turbocharging smaller automotive stuff but nothing on outboards. Stick to a minimum of 2 OMC fuel pumps?? Somewhere I heard that these OMCs also bring in water for racing different than stock fishing use. Is that adding on an extra line opposite each cylinder through the water jacket outer including what comes up the base? I am hearing that OMCs from 35 horsepower and up heat up real fast.
Actually from that 25 hour description that is taking a pounding at high rpm no fishing version would be put through is pretty dang good alright. Being a Merc fanatic (excluding 2 carb 3 holers) early on and for so long gives one false opinions based on the older non-loop OMC engines where I as others would term them being worked on by the hammer, screwdriver and crescent wrench crowd. Seeing what is going on these days on those and your engines by example would get one a poke in the eye or a vicious clubbing about the head for expressing such sentiments anymore for sure! LOL! Now I find myself being the enlightened and converted!:)
