Re: Feed back lines 300 xp 88
Look at the rev limiter on your motor. Its at 6700. E/J V8 outboards love rpm. Everybody set them up like a V6 and were unhappy with the results. Thats the main reason OMC quit selling them in the states but they were still quite popular overseas. <br /><br />Have I ever blown one up? Yep. We did a pair on a 27' Eliminator race boat. Mild porting, RCH heads etc. Had one of the fuel pumps quit and leaned her out at about 103. <br /><br />Have I seen others blown up? Sure. Were back to the same old reasons -- water in the oil tank, water in the fuel, dirty carbs etc. Same as any motor. <br /><br />I saw a couple 3.6's that guys wired the power packs side to side like a V6 rather than top 4 and bottom 4 like they're supposed to be. One of our "helpers" did that on our offshore race boat once. Sure it was my fault for not checking him before they tested. But I kinda had to yell at the driver for not coming back to the dock when he knew something was wrong. Trust me, from then on I did the testing.<br /><br />Yep, it burned a hole in a piston. The fix on the day before a race? We took the V8 off my fishing boat and raced that. No big deal. <br /><br />As for "over-reving" a two stroke needle bearing motor, I really dont know what that is. As long as it has a load the rpm is only limited by the rev limiter and once you by-pass that, by how much air it can get in and out.
