The engine starts very well when cold. After I've run it on the lake for 10 minutes or so and the engine is hot, I go to start the engine again it just keeps turning over and not starting. It takes aboat 10 times before it finally starts. I bought the boat and motor last year and took it into a marine shop to have this problem looked at. $380. dollars later I still have this problem. I don't know a lot about these motors, could it be the coils. Any help would be extremely appreciated.
Thank you, Don

A few things to check:

1. When it won't start, do you have a strong spark?. Get a cheap spark checker.
2. Is the primer bulb hard? It should be. If not, try pumping it up.
3. Any fuel dripping anywhere?

If the starter motor is defective it may not be cranking over fast enough to generate spark.-----Test the starter motor.

Take it back to the shop that fixed it and tell them you want it done right.

I vary my starting technique depending on how long it's been turned off for.

Immediate restart just hit key.
Restart after 20 minutes or so I treat as a stone cold restart with choke & fast idle.
0 to 20 minute restart is somewhere in between, perhaps a little fast idle or a tap on the choke.

They do cool down pretty quickly unlike a car.

Is this motor running at 100:1 mix or has that sticker been taken off and is it now running at the proper 50:1 ???

The motor will run good on 100;1 mix. It's only when you store it that you have problems.

You may want to start your own thread with your questions.

You will probably need to clean the carb.
