Re: Stus-List Adjustable Prop
Hi Ron, the original folding 2 blade on my 29mk2 was 14D and 8 pitch. Upgrade to Gori prop is 15 and 10 pitch. Magic will do a bit over 6 knots at 2000 rpm. Cheers, Bruce.

Stus-List Adjustable prop
I have an older, three blade, CD feathering prop on my 29-2. The boat will motor at 6 to 6.5 knots at 2800 RPM under most conditions. I usually run at 2600 RPM with a boat speed of ~ 6 knots. Last summer when trying to re-enter Frenchmans Bay with a headwind of 25 to 35 knots and a moderate chop (offshore wind) the best that I could get was 3.5 to 4 knots. Fair Winds, Bob Hickson, P. Eng.

Stus-List Adjustable Prop
I have a Vari Profile adjustable pitch feathering propeller. I am definitely in need of an adjustment in the forward position as I am only able to motor at about 5 knots on flat waters at about 2300 rpm. In one particularly strong blow I was unable to make any headway into the wind and waves. I had to bear off to gain some momentum and wiggle up to gain way. My theoretical hull speed is 6.5 knots. It would make sense to me to adjust the pitch to give me more speed and see how it performs this year. Is this the right approach or does anybody have better advice? Thanks, Ron Ander E.Y.C.

Re: Stus-List Adjustable Prop
Generally I would say that you should worry less about max boat speed and more about matching max rpm to full load. You should reach max rated rpm and not blow black smoke. All of this assumes a clean prop and bottom.

Re: Stus-List Adjustable Prop
Do you reach max rpm in neutral? If not it's not the prop.

Re: Stus-List Adjustable Prop
Another key indicator that the engine is straining besides black smoke is engine temperature, which should be 195 max. Diesels prefer to run loaded up and warm, but we throttle back to keep the temperature right. Another note: RPM meters are not always accurate. A hand held tachometer proved our OEM was off by several hundred revs. I too see a hull speed drop off in short waves and headwinds. Above winds of 20 knots, our hullspeed motoring in short seas typically drops a lot. We try to sail as much as possible in those conditions, but sometimes need to get around a sea buoy when motoring offers a quicker option straight upwind. The chop affects sailing speed too, and motoring 3 knots straight upwind can be quicker and easier on guests than sailing more distance at 5 kts in building seas. Of course it all depends on schedules and mood of the crew.

Re: Stus-List Adjustable Prop
The correct setting will allow your engine to reach maximum rpm (Nigel Calder says at least 90% of rated speed), under load (in gear) at full throttle. If you can't reach max rpm, you're over pitched. If you can run faster than max rpm, you're under pitched. Normal run speed is about eighty percent of max rpm. For anyone considering purchase of a feathering prop, get the largest diameter prop that will give you a clearance of 15% of the diameter of the prop between the prop and the hull. Three blade props run smoother than two blade, and are worth the extra money. Alan Bergen 35 Mk III Thirsty Rose City YC Portland, OR ___ This List is provided by the CC Photo Album.
