What's the best way to get water temp up in 40 degree water?
BBC V-drive with a belt driven pump and no T-stat.
In January I had the boat in 45 degree water and after 20 minutes running idle to under 4000 RPM, the water and oil temp needles never moved.
Gently pinch the inlet hose????
Just looking for a temporary "fix" until the water warms up.
