We have a 1980 carver mariner 33 with twin 350 crusaders. The starboard motor we cannot figure out what is happening. The motor starts perfectly, idles and has a ton of power. Problem is at about 2200 rpm the valve cover feeder tubes shoot out a thick white steam or smoke. This kills the motor at any high speed.
We had a compression check done and all is good. We had a leak down test done and no major issues found. all were within acceptable parameters according to the mechanic. So nobody can answer what is happening with the motor.
We thought head gasket but that was ruled out since there are no signs of water in the fuel....
I AM STUMPED! We have been through 4 mechanics and thousands of dollars and still cannot run our boat more that 7-8 knots.
Anybody every seen anything like this?
Thanks
