« on: April 14, 2016, 08:26:24 PM »So here's a dumb one. How is the HEI wired?this is what I got wire smaller gauge go back to ignition switch might that be a problem no resister anywhere
Hopefully to a fairly heavy wire from the ignition switch or a relay, with no resistor.
I got nothin'.

That's why I'm scratching my head on this one. Boat runs great just not hitting the rpm s think I'll try unbolting jet to check one more thing off the list

Boat new to us was told jet was rebuilt dominator bought a rebuilt motor just put new 850 on it no difference in rpm but runs alot better every where else timing at 34 total fuel pressure at 6 pounds at ideal have to check that on water under load to see if I might have a problem there boat runs great just rpm challenged replaced all gauges and they all stayed the same if I had a bearing issue should I have a noise because there is none

« on: April 14, 2016, 10:41:54 AM »Think I found the problem!
Probabley right my powerstroke runs bitchin maybe I should put that in it almost spins as high and fuel is cheaper

Can't see anything in pump did spin fine and do have full throttle. Is a head scratcher for sure probably be something easy I'm overlooking that's why I'm consulting the pros

Thanks on pump info know nothing about them at all first one I've owned. Sorry outboard convert like in earlier post switched from 750 edelbrock to 850 holley with better overall performance but still only 3900 rpm boat doesn't stumble at all just stops pulling will check fuel pressure next sure would be nice not to have to do a pump before the season

Bought eliminator day cruiser with blown motor, put rebuilt motor in and can't get more than 3800 rpm. Mild 454 dominator jet not sure what impeller or how to check! 850 double pumper! Hei ignition! Any info would be appreciated. Kinda stumped at this point
