What muffs are you using? Turning the water on full I hope?
Correct me if I am wrong but the Blue flush port is after the impeller. There should be no water going out your drive inputs when using the flush port. You need to pull your impeller.
Normal for one side to be hotter.
Next time you are in the water testing, put the engine at 100RPM. Remove the hose at the thermostat housing and output the water from that hose into a bucket for exactly 15 seconds. Should get around 2 gallons of water or so.
Does your bow thruster remain in the water for long periods of times....like overnight? Do you boat in saltwater? If either of these questions is no, I wouldn't worry about it.
I use a strap. Was tired of all the cable issues including the starands and the cable getting stuck on itself. These days, I only use the winch once a year on each of my trailers and they don't have to be pulled very far up the trailer thankfully.
His pump only uses the o-ring...the paper gaskets aren't used.
The 1346 is a kit I actually used on my belt driven Volvo pump. It is used for many versions both belt driven and crank driven whiuch is why it comes with paper gaskets as well as the o-ring.
All you have to do is make sure the engine is at TDC and the camshaft is aligned correctly. The shaft that rotates the distributor can be compensated for by rotating the distributor when you time the engine.
I was an amuteur the first time I replaced one of these. Fortunately, the B21 is a non interference engine so pretty hard to eff it up and damage anything.
I have done many of these on the same engine in the Volvo auto. It's probably the easiest timing belt I have ever come across. There are alignment markers on all the pulleys and typically on the belt too. Pretty hard to screw up.
The way the tensioner works is you loosen the bolt on the tensioner, allow it to tension the belt and then you tighten back up. If you don't the tensioner pulley will be loose and not be in alignment causing your belt to move like it is.
If the boat is plugged into shore power, I can see the problem. If a boat is not plugged in, there really should be no issue.
I may be adding an outlet on my dock and I would definitely do a voltage check to see if there was stray current.
My boat is in Lake Tahoe where the warmest the water gets is 65°F.
Those temperature stickers sound interesting. Where do you get them at?
I was thinking about putting some wireless BBQ probes on it to see what it gets up to.
