Hey everyone, I picked up a Stingray boat a few months ago, and have had my first BOAT issue.
So I have searched and found many conditions similar but have not found my resolution yet...
First off my serial number is 0M329027.
Background of Issue: I am have a rich running engine. At first it seemed to only happen when switching gears but now it is stalling at idle and is hard to start. Compression is fine, fuel pressure is 35-38 typically, I have read 43 is where it should be. When I purchased the boat, it started up great. I replaced the outdrive and have had the boat out and use on weekends. Recently the initial cold start up and idle has been poor.
Items I have Tried:
Ran 2 tanks of treated fuel through (Seafoam first tank, Lucas second tank)
Replaced the IAC - no change
Replaced all spark plugs - All plugs appeared OK except for black soot, which matches the rich condition theory
Replaced all spark plug wires.
Replaced fuel regulator
Removed AIC Muffler filter
The Engine still starts hard. In order for me to get the engine cranked, I have to knock it into neutral and rev the engine up, let is run for 5 minutes or so and then it shifts forward and reverse perfectly fine. I think the only thing that has really improved the stalling and idling issue is indeed the AIC Muffler filter. It definitely needed replacing. The engine accelerates flawlessly and will run 54mph at 5500 RPMs. Idling RPMS seems to be around 8-1000.
Right now I have injectors on order, my assumption is since they are 20 years old, I may as well replace them anyways. But want to make sure that i am chasing down the right repair...
Any ideas? Hope I got you all the correct information. Thanks!
