The manual said by cutting a 1" hole on top of the carb. will improve the speed.
I have not cut the hole yet and i am considering to do so.


Have you guys done that yet?

Does it really improve the speed?


Thanks

By cutting a hole in the top deck cover, above the carb, will allow fresh air to reach the carb. The engine will be able to breath better, and it will run better to boot !
A simpler way to do this is to not use the top deck cover at all. Run it with an open compartment, it will also help keep the temps down too, even though it is water cooled.

yes it helps lots, i also enlarged the two holes near the rear. IT helped with the top end , didnt really notice any extra water comin in(useually has a cup or so in it after 10 or so mins of runnig.)chuck

Thanks for the information guys,

My boat only have approx. 5-8 table spoon of water after 10 minutes run (without 1" hole cut out at the carb).

I wouldnt cut a hole in the hatch. Your just going to end up getting water in the hull and in the carb. If you want to see how it would run with a hole, just carefully run it with out the hatch.
