Hello,
Newbie here as well as my first post. Don't laugh but I have a question involving the proper procedure running water thru the engine in order to run the motor while the boat is on the trailer. Is there a connection for a hose? Is there a devise which hooks up to the jet intake as in outboard motors.
Although I am mechanically inclined, I've never worked on this type of set up. My friend wants me to find out why his boat suddenly dies after running for about five minutes on the lake. I suspect it's the fuel filter as the boat has been sitting for about a year. We've added new fuel as well as seafoam so the fuel shouldn't be a factor.  I simply want to run the engine while it is on the trailer and assess from there.
the only thing I now about the boat at this time is that is is a 1973 with a Buick V8 engine. I'll find out more is need be.
Thanks in advance!
