Khaleesea is out of the water. Looks like the barnacles took a toll on her paint. No blistering though. I'm going to leave her on the hard for the next 3 months to let her dry out.
Picked up the new prop today. After measuring the available space, I'm going with a 15x17x3 prop to replace the old 15x12x2, which is in less than stellar shape. I've brought it home for a bit of polishing and a shot of zinc galvanizing compound. I bought it used, because I'm a cheap bastard.
Don, the prop guy, has been incredibly patient with me and my extremely limited knowledge of props. He's a real craftsman, and was kind enough to lend me his prop puller so I could yank the old prop today.
I would have loved to try for a bigger prop, but unfortunately the 15" stock prop was already the absolute max diameter available for the space. It would take a serious amount of hull construction to go with a bigger prop, which isn't worth it.
This sets my gear ratio at 2:1, so no whacky custom parts will be necessary.
Unfortunately, the BMS is turning into a thornier problem than I had anticipated. Looks like I might have to go with an off-the-shelf BMS and see if I can adapt it to my needs. I didn't even know they existed, but fortunately, they do.
Looks like I'll need a few more boat bux to finish this project. Good thing I didn't set a hard budget for it.
