I truly appreciate this information....hope this turns out to be a quick/cheap fix!! Thanks,

I would start at the tank anti-siphon valve, if you haven't already done that. It needs to be looked at/cleaned anyway, is easy, and the specific problem it causes is bogging at higher load/rpm and then difficulty recovering. Brian's suggestion of running off a small remote tank is a good one, eliminates a few possibly causes, but like he said if you aren't able to do that start at the tank and move forward.

If you bring the engine back to idle when it starts to bog down will the engine continue to idle. I had what sounds to be the same issue on my 92 excel. The issue was float needle valve assembly was plugged with what looked like leaves or organic material of some sort. If possible run on a external fuel tank hooked to the mechanical fuel pump. This will eliminate any issues with your fuel system up to the mechanical pump. If the issue continues then you don't have a tank, anti siphon valve, tank vent, or line issue. Next I would check the mechanical pump pressure. I tested mine and read 6psi, but I replaced for "troubleshooting" as it was the original. If that tests good, then most likely a carb issue. I would also double check your timing, pull spark plugs and replace if needed.

Crank/ Start/ Choke.....you know what I mean and with all due respect, I would rather have your advice on these issues versus old worn out jokes....the sooner the repair the sooner we're all back on the water....since you're full of jokes,...do you have any advice?

Cam,
Sorry but evidently you didn't get the meaning the first time. My pointing out the difference wasn't a joke. As mentioned, it is a attempt to clarify. "crank/start/choke all have different meanings.

My advice? When it happens again, check for spark and fuel. Then we can go with a direction.

BTW, You should have an automatic choke and the reason I asked how you are choking the engine.

8122pbrainard wrote: Cam, Just for clarification to avoid any confusion, when you say "crank", you mean engine is running? The typical use of "crank" is the starter is ungauged turning the engine over but the engine isn't running yet. He's cranking: How are you choking the engine?

I'm hoping this thread will help me as well....last summer my "89 started coughing and bogging down a few times under normal throttle....if it didn't start back immediately...it would crank after I let it sit for a few mins and maybe a little choke...that only happened a few times on one particular day...after that, I had no issues the rest of the Summer...fast forward to Thurs when I finally got the chance to put in for the first time...it cranked no problems...I idled for a bit then drove a short ways to the marina to fill up....drove around 20-25mph for 10-15mins then it bogged down again....this continued to happen multiple times the rest of the afternoon and I ended up using the better part of the afternoon trying to diagnose when it was specifically happening....

It idles great....engaging into gear and low speeds 5-15 mph it doesn't burp at all....upwards of 20+ it can run for 2-5mins like a top then all of a sudden it will bog down and shut off ...same thing...will either crank back up immediately or with a bit of choke...if not, I can let it sit for 3-4 mins and it will crank right up like nothing happened.

Hoping to get some direction and not start throwing parts at it unknowingly...thanks for the advice.

David,
Do you know if the carb has ever been rebuilt? Sounds like it may need one. You can also check to see if the accelerator pump is working. When you give it gas, you should be able to look down the throat of the carb and see gas squirting

Lay off the starter fluid. Worst thing you can spray into and engine. The high solvency washes the oil off the walls of the cylinders.
