Hey guys, recently began dropping a yamaha 1100 into a Blaster 2 hull and everything has been going decently
Just recently noticed that the incoming cooling line from the pump is a 3/8”ID That originally fed the manifold of a 760 motor as typical
The 1100 motor is fed at the manifold with a 1/2” water line from the pump/fitting
If I adapt the 3/8” waterline to a 1/2” and continue to use the smaller cooling line
Will it provide enough water to cool the bigger motor
Or should I just bite the bullet and tap a 1/2 fitting into the pump now
These motors are already prone to melting the rear cylinder (seems nobody is sure if it’s a cooling route or a fuel delivery problem) and id hate to melt a brand new piston
I know the water pressure is decently high regardless of the fitting size from the pump but would there be enough volume? Maybe I could just slow the rate the water exits the jacket to compensate?
Any advice would help! Thanks guys
