Yes Chris i am happy with the 'eggbeater'.I run a marinized rodeo 2-2ltr diesel,because its not a marine diesel it was a little higher on rpms.Behind that a 2:1 ratio marine gearbox.I tried a cv joint,it works well but im going back to the uni joint.The 1" shaft has a casing with 3 teflon cutlass bearings lubricated from the top of the shaft from a bypass in the engine saltwater exhaust cooling.The V lifter with locking latch works well also although i have another lifting method which will also lock the shaft down using an old large spreader.The salt water cooling pickup is just down between the fin and the prop and works a treat also.All in all some fine tuning but the system works well

Gday Chris,the prop size im swinging is 21" 3 blade left hand.As you may be aware there are a few things come into the equasion to determine what size of prop you can swing to suit your boat and running gear.Basically,hull waterlength,hull shape [type of /and displacement],average engine revs max when underway,gearbox ratio.There are equasions that will get you near enough to your target.[Look up propeller calculator].Im using close to 2ltrs an hour and cruise 7kts at at about 1800rpm.I can put another 600rpm into the box and should bring speed up to @10kts if i need it.

Hi Dave thanks a lot for the info.I have tiki38 plans and am making final design choices .2 outboards or a big diesel type of stuff.I like simple stuff and being a mechanic the old style diesel is first prize.Sounds like your system works well.and is quite efficient.Regards Chris

We are John and Kat from Australia, members of the PCA and we are building a 42' Pahi due to launch in about a year. We will be in Cape Town on 4/5 February and Durban on 7th February. If you are going to be in the area and would be happy to meet with us to discuss Wharram building and owning, we would enjoy it very much. Please let us know as soon as possible.
John and Kat
