Hi Brad and all,
I met up with Nick at Quantum in Port Washington; we dropped his car off at the town dock and drove over to my boat in Sea Cliff where we sailed back around to PW and rafted up. Nick was called away by his wife and I went on to raft up with Hugo right outside of Leed's Pond. It was great meeting these guys. We don't have any specific plans to "cruise" together yet but it seems like we will definitely be putting some trips together going forward.
At this moment, I know I am interested in the trip to Montauk at the end of the month, whether it's convoying or going with you. If I can get my overheating problem under control, then I think I would like to take my boat and anchor close or raft up.
When Nick and I headed out of Sea Cliff, the wind was on our bow so we motored out. I kept the boat at a very high RPM of 2200-2300 and eventually watched the temp climb sky high. It seems that if I keep it at around 1800, I don't have any problems (I still have to test that for a couple of hours straight) but when I get greedy and want to achieve my staggering 6.2kts hull speed, it starts to overheat. As I decrease throttle, the engine alarm comes on while the engine is still running unless I increase the rpms which of course, exacerbates the problem.
I'm writing this here, and will post it in a more appropriate forum, to see if anyone has any other suggestions.
Here's what I've done:
Checked the impeller - everything is intact
Impeller does not spin freely by hand and spins when the engine is started (I left the cover off and started it)
Replaced impeller and cover - no leaks
Good flow of water from the sea ****
Ran the hose from the dock directly to the engine (I have a T-connection) water rushes through as it should
Repeated muriatic acid flush last night
Last year it remedied the prob and restored good flow (I'm just not sure if I ran it at such high rpms afterward)
I'm going back today to flush the acid out and check it
I tested the situation when I was coming back from PW last night (because I'm stupid) and wound up coming close to overheating again but because there was no wind, I kept it running at idle @ 180 to 200 degrees while I limped back in to my slip at 1.2kts.
After flushing the acid out, I plan on checking and cleaning the bottom near the intake, but again, there is reasonable flow from the sea **** so I don't think that's the problem.
Any thoughts or suggestions would be appreciated.
Brad, good luck with the keel work; I hope it goes quickly and that you're able to get out soon. If you feel the need to sail before then, I'm right around the corner from you and would happy to take you out. If you need help with your keel, I can only provide comic relief and add extra hours to the job...if that sounds like something you need, let me know.
