If you leave your boat in the water for the winter, but don’t use it until the spring, how often do you start your engines and how long do you let them run? KJ

A four stroke may not be a critical as the cylinders of closed,
Agree...I get my single up to 180 degrees or so (about the same as my slow cruise) in about 10 minutes at 12-1400 rpm with no threat to any cleats or dock...the higher rpm is usually in reverse so it's way less pressure on the dock.I run mine every couple of weeks at a minimum and at about 1000 RPM I can get them up to temp in about a half hour against the cleats.

You are not comming south this winter ?
Reverse at high RPMs is also a good test of your shaft coupling shear pins and set screws. If you pull your shaft from the coupling its best to do it at the dock.
When I surveyed mine, I noticed stainless clamps on each shaft. A foot or so forward of each seal. When I was looking at them, the surveyor said that was good trick to keep your shaft in the boat if you sheared one. The drag can pull them backwards and out of the boat otherwise.
During periods of non-use I like to crank the engine twice for two 10 second periods every 30 days. Distributes lube oil, exercises rings and oil seals.
Poker,
Mine won't start anyway w/o the glow plugs but wish I had a compression release.
Everybody seems to think an engine is at operating temperature if the coolant is up. NOT SO. Basic parts like pistons and valves are still relatively cool. That's the core of the issue w under loading. Idling at the float in or out of gear dosn't mean you have a significant load. My Mitsu warms up to 185 degrees coolant temp in just a few minutes in neutral. Running at a 50% load will probably do the trick but that's far cooler than a 75% load. And I'm not talking 50 & 75% of throttle or rpm either. 50% load is at whatever rpm your engine burns half of it's maximum fuel consumption at WOT.

I totally agree with all of these points but many on this forum do not, according to posts on similar threads.
I don't see any "Gross misrepresentation" just a couple of guys describing their own practices and beliefs.
Exactly....
