Re: How does a Johnson 130HP V4 compare with a 125 MERC inline-4 ?
I don't know much about the OMC's to tell you what the most effective mods are but there are quite a few OMC gurus on the other board that can help with that motor if going faster is what your after. You won't find much help with Mercs until you talk v-6's.<br />I can tell you from personal experience though that if what your after is an extra 5 or 10 mph then playing with different setups, carbs, or exhaust chest mods can be fun to mess with. But if your after a 65 mph bayliner you're much better off finding a hydrostream or checkmate that is better suited to take the power.<br />Two other alternative power options would be a v-4 yammy or inline suzuki. The yammy's are supposed to be very reliable and there are some people to help with mods for those too. The suzuki's are also reliale, 115 powerhead is very similiar to the 140 powerhead, and I've been finding them used pretty cheap lately. But, parts and service suck and your on your own with mods. But I'll say it again if you want to go fast then buy a cheap force or inline merc, sell it, and then buy your self something else.
