Just snagged this boat from my good friend. 1985 23' Wellcraft Nova XL with a 454 Magnum 7.4L.
Issue:
While Idling, the temp goes well over 200* (gauge stops at 240*) and the alarm goes off. When at WOT (only 4000 RPMs), the temp comes down to approximately 160*-180*. Between 2000 RPMs and 3000...
I had gear lube in my bellows, therefore I decided to change the oil seal. I've removed everything and I've changed the seal (U Joints also), and I've reassembled the drive gear through the retainer (a-j in the picture). I've tightened the nut far enough to where there isn't any play. Before I...

Re: Mercruiser 350 Alignment Issues
On the rear mounts, I have the fiber washer with the lock nut inside of in on the transom mount, then the actual flywheel housing laying flush, then the spacer, then the washer, then the bolt torqued at 45 lbs. Like this diagram. I've also been adjusting it...
Ok, on to my next can of worms. I've recently had to rebuild my engine mounts as they were rotted in my 83' Wellcraft Nova. I was actually out in the channel and the engine dropped through the glass and mounts, stripping the splines in the coupler smooth. As a result, I pulled the engine...
Hello fellas,
I just finished rebuilding my 350 (260hp) and I cannot get it to start. I have it in my garage. I wanted to test it out for leaks and any nonsense before I stick it back into the boat and then have to work on it in there for any reason. This engine has a Thunderbolt IV ignition...
Just bought a 1983 Wellcraft Nova 23' with a Mercruiser 260 HP in it. Everything runs great on this boat. I've seen the boat perform the last 3 years, it belonged to a friend of mine, whom I just bought it from. I want to do some general engine maintenance on it before I put it in the water. Can...
I'm having trouble finding a post with exactly what I'm looking for. I'm not sure if I have to put this engine into base timing mode. I time it at 8* before, just by hooking the timing light up (without putting it into base timing mode). If possible, is there a manual that shows what the mixture...
Re: Merc 140hp overheating issue
This is more than likely the culprit behind the overheating
The hose isn't kinked, I checked it and contorted it in every angle that the steering and trim would allow right after I installed it. I checked again tonight. It's good. I also replaced the exhaust...
I took the boat on the Chagrin River (Eastlake, Ohio) on Saturday. Was just taking it easy as it was the first time out. The engine quickly overheated and started to stall. The temp gauge pegged out at 260 degrees+. I'm going to replace the thermostat as well as the impeller. My question is if...
I've watched the video on youtube by aChris, http://www.youtube.com/watch?v=-s_tgevX2aI I've followed these adjustments to the T. I did this once before with old cables, and it still didn't work, so I went and got brand new cables thinking the old ones were stretched, and I'm still getting the...
I've adjusted both cables numerous times, and I just can't seem to get it right. My problem is that when I try to shift the drive either forward or in reverse, the gears crash for a second, then engage, easier forward then in reverse. The shift cutout switch barely engages either way. When...
I finally started the engine today after a few failed tries, broke down and rebuilt the carb with the help of my brother-in-law, and it fired right up after the rebuild and cleaning. What we couldn't figure out is why the choke was wide open as soon as we plugged the connectors up. There is some...
