Based on this, I think your engine may last many more years if it's oiled properly and you don't run it very had WOT for long periods.
I don't recommend running on the hose, thus I don't run my boat more than 30secs out of water. Mainly b/c there's too much chance of leaving water in the exhaust that causes corrosion, and it's too awkward to connect hose, turn on, turn off, etc.
30 seconds of running should say enough to know if boat is splash worthy, and it's enough to distribute the normal amount of oil onto the cylinder liner, and approximately duplicate the conditions of running.
I feel if the engine is sitting clod for days, the oil runs down off the cylinder sleeve back into the crankcase, thus ring seal is not going to be as good. Synthetic oils don't stick well to cold surfaces either, they run off quicker, this is why I prefer using non-synthetic for fogging when the choice is available.
110 stone cold is perhaps a little low on the one, but I wouldn't worry about it as long as that cylinder is still firing normally and you don't plan to become speed racer.
Your comments are encouraging :-D
I found it is kind stressful too when doing the hose on and off timing, especially with a few "immediately" terms in the manual instruction.
I will check if the small bottle I bought for the "oil cable back up plan" is synthetic or non-synthetic. If not I will get a bottle for the syringe.
This blue boat is for family, no speed racer. Tried to pump up the 3 seat Sea-Doo tube (about 7 feet wide), it is very nice and comfortable to sit on, it has a back too. So cruising at 20MPH, and towing at 10MPH maybe the maximum usage I would expect from her.
But I may get more into this jet boating thing in 2 or 3 years after I am more comfortable with the thingy involved in jet boats. Plus I love to be able to work with into engines and jet pumps.
