Sounds good. I plan to drain the oil when I get back to it and check for water. Then I'll start engine disassembly. Might be a week or so before I can get back to the project, but I'll keep you all updated once I get there.
Well folks, I think we've identified a major problem here. Did a compression test today and the results are as follows. Cylinder numbers are basic chevy 350 pattern.
Cyl 1 200psi
Cyl 3 185psi
Cyl 5 190psi
Cyl 7 195 psi
Cyl 2 198 psi
Cyl 4 35 psi
Cyl 6 0 psi
Cyl 8 200 psi
Seems like we're looking...
They were put in last year by a shop. I'd say maybe 10 hours idle, 10 hours cruise, couple hours WOT, knowing that WOT is only hitting 4k rpm with whatever issue I'm having.
Spark plugs. Delco #MR43LTS Aligned in the photo how they came out of the engine. Closest plugs near the belt. A few electrodes shown close-up for detail.
Starboard side, same deal. Did notice where there must have been a small water leak...unsure if this is an issue or just needed more tightening on the hose clamp
Alright, went through a few things today. Here's my findings. Pulled elbows and inspected risers and exhaust flappers. Risers look good to me, excellent honestly, for a boat that's likely never had them replaced. Very little rust/corrosion. Flappers are in place and whole although they do make a...
Well, thanks everyone for the warnings about my large tub of water idea. Looks like I'll have to ask a friend to borrow their driveway to run it on muffs. Going to check some basic things today - Pull plugs and inspect, check exhaust flappers, check fuel pickup line and check valve...etc...
I apologize for the abrupt ending there...had some connection issues with the website. The post was supposed to continue as follows: Now, I live in an apartment and don't have access to a spigot for running it on muffs. I am hoping to do compression/timing/fuel pressure tests running it at my...
Actually, the engine and drive oil were changed twice within a month...once at the shop who 'checked' the distributor and again at the shop I had winterize it. I didn't ask them to change oils with the winterization and didn't know they had until I saw the bill. Guess I should have asked more...
Absolutely, I'm ready and prepared to do some serious troubleshooting. I know the engine and drive oils have been changed as I had a shop perform that last year. Engine oil reads over full which I know has been said can be a cause of poor performance, but I've always checked it on the trailer...
Hello all,
I've been pouring over dozens of old threads the last few weeks trying to sort out some issues I'm having, but was mostly just trying small, inexpensive fixes. After this weekend, I decided to find a shop to work on my boat. Unfortunately, no one in my area particularly wants to work...
