rebuild or buy another?

[dctroxel]

Had zero compression on one of my cylinders on a 1987 110 Johnson VRO. After removing the head, it looks bad inside, lots of scoring on the cylinder and slack in the cam bearings. Do I drop the $2500 to rebuild this one or buy the dealers used 1995 Evinrude 120 VRO for the same money? Either way, I get the same warranty. Any advice would be appreciated

Yes, If you have a reputable mechanic, rebuild your powerhead. You need to know condition of your gearcase, etc... Replacement ignition parts might be cheaper on the '87. Compare corrosion on both engines.

Depends how many hours are on the '95 and what kind of maintenence history. You'll be getting an eight year newer motor, 10 more horses, and the same warranty. Tough call. I guess it's like deciding to remarry.

Properly rebuilt is a lot better than used.That makes it new.<br /><br />DHP<br />OH same wife 35 years,if that is needed

There is no way -- no way -- to compare those 2 motors. The crossflow is 1950 technology vs 80's technology of the looper. The looper makes a ton more torque than the cf. <br /><br />Especially if the crossflow has slack in the cam bearings. I bet it doesnt though.

And the looper doesn't have any cam bearings to get slack in. <br />Couldn't help myself.

What is the difference between "CROSSFLOW" and "LOOPER"?

Re: rebuild or buy another?

its to do with the port design. The cross flow has all the inlet ports on one side, and the exaust ports on the opposite side of the cylinder wall. The piston usually has a deflector on top of it which helps direct the incoming fuel/air charge up to ward the top of the chamber, at the same time, this helps push the last of the exaust gases out. The "looper" is loop charged, which (in the few engines I've worked on) has the inlet ports opposite and beside the exaust port (sorry if that sounds confusing, it's late here and I need sleep).<br />The piston does not have a deflector, but usually a domed top. Dhadley or someone with similar experiance (this guy races these motors) can tell you more info about how they work.

I guarantee you if you drop that 120 on your boat (and assuming the looper is healthy) you wont care how its done, you'll just know theres a night and day difference.<br /><br />Actually to me its a no-brainer;<br /><br />You obviously like the boat.<br />Its a given that a set price will get you back on the water and youre willing to spend that.<br />The looper is a much stronger motor.<br />The looper is 18 years newer.<br />Its a direct swap (no changing the controls or harness)<br />No waiting. (Assuming the looper is a used, ready to go deal)<br />The looper will use less fuel.<br />The looper will be quicker.<br />The looper will be faster.<br />Same warranty.<br /><br /><br />The ONLY downside I can think of is that the looper is heavier and if the boat is kinda small, that may be a concern. Other than that -- why isnt the looper on the boat yet? We could be fishin!

Cam bearings? Please explain what these are.
