I have a 70hp 4stroke eng on a 16 ft boat. Engine cuts out while i am accelerating to plane. eng retsrts diff?

Question

saltwater water seperator eng 18 mths old 120 hrs.

Answer 1

Reading between the lines, is the bow of your boat very high during acceleration?  Does it take a little time for the boat to get on plane?      Was the engine "winterized " last winter, and running normally when last used?    I'm thinking that the carb(s) needs cleaning.

Answer 2

theres a cooling water pickup on the bottom leg of the engine. when you go to plane it leaves  the water and the engine does'nt get the water to cool it so it cuts out. Nes Pas??

its a safety feature.

So if you want to run that size engine on that boat you have to keep the rpms down.

Answer 3

I think it is a fuel to carb issue have you tried renewing the filter/ seperator?
