Re: Boat running hot on plane PLEASE HELP
That's excellent info.
At least you know pretty much now it's not the engine itself. The bubbles and the half filled hoses clearly indicate insufficient amounts of water getting from the pump to the engine. As to the true source of the problem, it's likely leaking seals but the big question is which seals and that is not something you are going to be able to figure out on your own if you are not capable of tearing into the outdrive.
On my last boat, an '86 25' Bayliner, when I finally figured out my seals were leaking (1.5 years later after a series of overheats) I was not capable then of doing the work myself because I did not have a trailer to pull the boat out. I had to pay the marina $1800 (your's likely won't be that much!!) to reseal the entire outdrive with new gaskets and O-rings but it did resolve the problem.
My current 16' Evinrude boat is out in my carport and I just finished resealing it myself after doing a lot of reading. It's not that difficult if you have some mechanical aptitude, a good tool kit, a good manual and some good moral support.
At this point you have a decision to make. If you are not capable of working on the outdrive yourself, you're going to have to take it somewhere to have the work done. But at least you know where the problem lies.
