| Took the boat out for maden voyage after successfull sea trial and after running (great) it wouldn't crank:( After it cooled down awhile it sounded like it wanted to start but didn't..It has plenty of fire and fuel getting to filter on side of motor>>>any thoughts/ideas I can try before I take it in? I am thinking there may be another fuel pick up between engine side mounted fule filter and carbs...any Nissan knowlegeable folks out there? Appreciate any thoughts offered. Thanks for you help! Jimmy

If it is stumbling as it tries to start, there may be water in the fuel system. I would do a compression check to start for the heck of it.

| Well, this morning the motor started and I ran her for 15 min and no propblems...then started her several times after and ran fine..maybe vapor lock somewhere in the fuel system...hope problem solved...one other thing, I replace service fuel line with a 3/8 instead of 1/4 inch line from manufacture...could this made a difference? I did that because the 3/8 was all I could find on short notice..Should I put back 1/4 fuel line...didn't think it would make a difference as long as engine recieved steady flow of fuel..

I would go with the original size. If it is the fuel line from the tank to the engine, I would go with no bigger than 5/16". Usually 1/4" supply line on a 90hp is small. The mfg will use 1/4" after the fuel pump.

| Double D, Thanks for the advice...it is the service fuel line from the tank to motor I changed from 1/4 in to 3/8 in a desperate attempt to get on the water. Boaters world smallest fuel line was 3/8...By what you say I may be ok with 3/8 inch but should switch back to manufactured size...correct? Jimmy
