Evinrude v-4 low compression on one
I'm looking at another boat. A 19 ft bowrider trihull. the boat
itself is in great condition but the 100 hp. v-4 Evinrude has ow compression on one cyl. they burned up a starter trying to get it running. they got a starter put on and found out one cycl. is low. Didn't say how low, but it's still not up with the other 3. They were thinking on fixing it, but decided to get another boat and so they're wanting to sell this one. Cheap! i mean, the lower end on the engine is probably what they want for the whole thing... Cheap! I know that that to repair the engine is going to cost something. It could be anything from a bad ring to a scored piston and cylinder. , But I'm not too worried about it because I have a 115 v-4 in my garage with a one year old power head. But I'd rather see how bad the engine actually is before I swapped it out. If a cylinder is scored that's one thing, but if it needs a piston and/or rings that's another. I don't know much about the v-4's but can you pull a piston without having pull the flywheel and split the casings etc? The engine is a 1979 Evinrude Javilin squared hood. just curious. |

Tim, I don't think you have to. I know that on a '75 that I had, it had a crankcase cover that unbolted to get you to the rod bolts. I scored a piston on that one, too. Took the head off of that side, took the crankcase cover off after removing what needed removing, carbs, etc, took piston out, took jug to the machine shop oversized the cylinder, bought .020 over piston and rings, then re-assembled. |

If you look on this site, assuming the URL works: http://shop2.evinrude.com/ext/index....6c0e5618648963 You're see an exploded view of that powerhead. I don't see how you can remove a piston without splitting the casings. How would you get to the wrist pin? Here's the piston drawing: http://shop2.evinrude.com/ext/index....6c0e5618648963 |

Like my precious bodily fluids are being drawn off. Can't wait until November. In the meantime, I'll just spoof anybody who says the wrong thing. Easy, no thinking, and provides sense of power. It works! |

The way i see it, if you can remove the intake manifold, and a plate (if there is such a thing) off the bottom (crank side) of the engine and get to the connecting rod and pull the nuts from the bottom of the rod, and take the head[s] off, you should be able to push the piston/ conrod through the top of the engine, like you would on most reciprocating engines. |

Well...there's every chance you could be right! You're also assuming, I would guess, that a frozed or damaged piston and rings are the only problems in that powerhead. It's 30 years old. Restoring it to operating condition may well take a lot of time and a significant amount of $$$. Oh...the gearcase could be shot, too. |

True, but I 'm really not concerned about it because i do have an older 115 hp v-4 with a new power head. Well, it ws run for a year after replacement, then they wrecked the boat, then pulled the engine and mothballed it. It sat for almost 20 years in storage, and I bought it for a hundred bucks . Last year we build a stand for it, hosed and fired it. It ran well. So i do have a good spare, but I was hoping to use it on a pontoon if I can find one worth the money. Thatss why I'd like to get this one figured out if and see if it's something minor as a head gasket, or rings. The trailer is worth what I'm giving for the whole deal. |

Therefore, no one would know if it had low compression on one cylinder. |

Standard procedu unbolt the rod from the crankshaft, push the pistion/rod assembly out. That simple. |
