RichCarterParticipantThe photo below shows how far the propeller shaft is offset on my boat (hull
#47).http://www.richardcarter.net/boat/pix/chainplate/prop1.JPG
As seen from the side, a 3-blade slipstream.

ParticipantSo Rich, How do you get your boat home? HOw much stuff
do you have to take off? Do you live far from the
water? Must be nice to have it right outside you door.

ParticipantRich:
I noticed two things in your photo that caught my attention. 1. You seem to
have mounted the cutting block for your spurs on the starboard side of the
strut. Mine is mounted on the port side. Which is correct? 2. Your zinc is
mounted directly in front of the strut, blocking water flow to the cutlass
bearing forward opening. I have read that it is best to mount the zinc at
least 5 inches forward of the strut to allow water flow into the cutlass
bearing, since the water lubes the bearing.Please let me know your opinion. Thanks!

We have a couple of acres, so there’s no problem with space. The house sits on what was once a farm. The land is as flat as a pancake. We have the boat shipped overland by a marine transportation company. I need to remove the mast of course and any antennae that stick up higher than the davits. Other than that, nothing else needs to be removed. The photo below shows the boat in storage. It was taken about 5 years ago. If you look closely, you can see my daughter on the radio tower. That’s as high as I would let her climb, about 30 feet.We added the deck on the side of the house just to make working on the boat easier. The stairs make climbing up and down much easier than a ladder, and the deck makes a good place to work. The underside of the deck is used as a carport. We have a 30 Amp outlet on the side of the house. Having it home allows us to work an hour or two in the evening without having to drive to a boat yard. Tools such as table-saw, drill press, etc are handy in the garage or can be carried up to the deck if there’s a lot of work to be done. I even ran a cable-TV connection out to the boat so I can hide there when levels of estrogen get too high in the house.
We live about 50 miles from the coast. It runs us about $600 shipping each way.

It would be odd that the direction of engine rotation would be wrong. Most gear reducing transmissions reverse the direction of rotation. Your local Yanmar dealer should be able to help settle this question.I love the prop. I see no loss of performance in forward and reverse works well too. Under sail, it folds with no problem. I see about 3/4 kt improvement in boat speed. My prop is exposed however. If yours is inside a skeg, you may see less benefit.
http://www.richardcarter.net/boat/pix/chainplate/prop2.JPGPlease keep me posted as to progress. I’m curious to see how it works out.

I don’t think it matters which side of the strut you mount the spurs. I must have been sitting on the starboard side when I mounted it.The zinc isn’t really up against the strut. There’s about a half-inch of space. I have it close so as to minimize drag. I hadn’t heard about any problems regarding restriction of water flow due to placement of the zinc, but I’ll investigate.
