Re: Hot Start Problem

Are you re-pumping the bulb after sitting that long?

Re: Hot Start Problem

I am better at the older motors but here's a question ... is this motor new enough to have a computer in it that records various engine parameters? If so, you might be better off paying for an hour of diagnostic time to let the dealer determine the problem via the computer. Given the cost of parts these days, trying to fix something by random parts replacement, might be a great deal more expensive in the long run.

Re: Hot Start Problem

Are you using the warmup lever when you restart? It may be flooding while it sits for that hour, my 60hp johnson does that sometimes. Open the throttle with the warmup lever it fires right up. If I don't use the warmup lever to open the throttle I have to crank it quite a while to get it to start. Even though yours is fuel injected it may have a seeping injector that floods it while it sits.

Re: Hot Start Problem

Yeah I meant fast idle, My outboards all have a seperate lever for fast idle (warmup). I don't know anything about fuelinjected outboards, I've had cars that had "bad" injectors that leaked fuel after the engine shut off. The leaked fuel made it hard to restart the engine after it set for 15-30 min. I don't know how to look for bad injector on your outboard, on the cars I just removed the injectors, then was able to put fuel pressure to them and look for leaky tips. If you have "extra" fuel leaking into the intake, opening the trhottle with the fast idle will help it start.

Re: Hot Start Problem

I looked up the parts list of your motor, It looks like it uses atomotive type injectors, and an electic fuel pump to supply the high fuel pressure for the EFI. If you can pull the injectors out of the intake while leaving them hitched to the fuel rail, you should be able to check for leaks by running the fuelpump to pressure up the system. Any leaking injectors will be obvious.

Re: Hot Start Problem

Don't feel bad about not wanting to jump in there and take it apart, even the simple old carb motors like I have intimidate very smart people. If your not at ease with working on something it's better to take it to the pros, it will be easier on your mind that way. I'm not a pro, but I've worked on most everything from chainsaws to railroad locomotives, so sometimes I get carried away with my suggestions, I forget that everyone hasn't been turning wrenches for 25 years. Good luck, I hope the mechanic is able to fix it for you and you get alot of enjoyment out of your boat.

Re: Hot Start Problem

A computer diagnostic on a car won't show a leaking fuel injector, so I wonder if it will show up on a boat motor computer diagnosis? Did the shop hitch up a pressure gauge on the high pressure part of the fuel system?If it came back with a clean bill of health on the computer diagnosis, that means the electrical parts of the system are probably OK, but that doesn't tell you much else.
