Small prop for sailboat inboard
I need a 12" x 8"P right-handed prop (1" shaft) for my Cape Dory 28 and I can't seem to find one anywhere, save a new one for nearly $600. That's half what I paid for my engine! Does anyone happen to have one, or (more likely) know a used part place that has a good selection of props? Or I've called a couple dozen places but it's such an odd, small size that I haven't turned up any leads...

Re: Small prop for sailboat inboard
That IS a tiny wheel. What have you got , an 8 hp?
Is this a replacement prop, or what the numbers call for ?

Re: Small prop for sailboat inboard
I'd call Millers Island Prop in Maryland, or Kastel Brothers in St Michaels maryland, or Bacon Sails in Annapolis Maryland.
They all have quite a supply of used props, and since there are a lot of small boats in the area, likely they'll have something that will fit or can be repitched...

I have a two blade that fits that description or is close, 150 usd plus shipping. I'll check when I get home and let you know.

Re: Small prop for sailboat inboard
I may have this prop...it is new and unused. I will check it out. You can have it for pretty cheap. Does your shaft have a keyway? Bob

Mine is a 13 x 9, close, if you're interested.

Re: Small prop for sailboat inboard
Wow, thanks. I was about ready to give up hope so this is very heartening! PM's sent.
It is a very small engine (7hp) on a small (but heavy) boat, a Cape Dory 28 weighing in at 9-10,000lbs. I got the boat without engine or prop so I'm starting blind here but 12 x 8 is what I was told by a couple prop guys. I'm not likely to do a lot of motor-sailing so the prop isn't a great concern to me. It will be nice to have in tight spots but I am a bit concerned that being so underpowered will mean the engine isn't doing much in heavy seas where I might need it most. Can anyone familiar with two-vs-three blade props give me a sense of how these numbers would change for a two blade, or is it more complicated than a simple conversion? As I understand it you just need a bit more surface area on each blade to make up roughly the same area for the entire prop?

Re: Small prop for sailboat inboard
First off, are you SURE it's right-hand? My cd28 w/ Volvo md2b takes a left hand prop.
Second, I bought a brand new Campbell sailor a year and change ago, cost around $350 straight from the manufacturer.
I would recommend this particular prop highly for your boat - mine easily does hull speed and backs down nicely

If you are willing to go plastic you can get one for about $250.
My understanding is that in exchange for some durability you get a prop that is better for fuel economy. At high loads/rpms it flattens out slightly delivering full power and at lower load/rpm it ramps up giving better fuel economy.

Re: Small prop for sailboat inboard
The wee motor will probably do nothing for you in heavy seas or against strong winds.
4, or 5 in a calm, or helping to point a little higher in semi nasty conditions.
