Hey...I just hit a rock in Bayport Fl. and I need to repair or by a prop. I do not have it hauled yet. I think it is a 17/12 LH 1 1/8 3 blade. Does that shaft size sound right for a 365 ketch with a Westerbeke 40 with a v-drive?
Others will probably be more help, but here is a link to another prop size discussion. I would think getting a rock to hit the prop would take some effort. :)

Mine is slightly different than the Ketch
The shaft size is indeed 1 1/8".

Indeed...it takes more than your average sailor to motor over a rock...Bayport is very shallow...I mis \read my GPS...I did not trust it...and I should have....but the rock patches are over sandy bottom. Since my prop is about a foot above the keel...at 3 to 4 knots motoring...I bounce right over the out croping and when the boat settled...the prop made this awful noise....I wish I had been under sail....
I have a MaxProp 17" 1 1/8" shaft 3 blade classic set to 12" left hand pitch, and it seems perfect for the W40. Full throttle gives me about 6 1/2 knots with 2400 RPM.
Shaft is 1 1/8". Correct prop 3 bladed is 17x 12 LH. My prop is 17x12 and works great. Let us hope you don't have gear box or V-drive damage if the prop was turning when it hit.
How would I be able to tell if the v-drive or gear box damage?
Noise, slippage, oil leak(s), overheating, wobbly shafts for example. On the other hand "don't fix what ain't broke".
Thanks...I will get in my look..listen and feel mode
Carl,
Let me know if you ever go into aircraft maintenance cause I will stop flying. Speaking of broken, how are you doing on your issues? Are you back to the boat yet?
Dale
I got the prop off with out hauling the boat...I am so confused....It is supposed to be a 17/12 LH..1 1/8...When I get it to the shop tomorow i will find out what it truly is....It is stamped...17 R 10...1 1/4..with a sleve to reduce to 1 1/8 ....that seems to be imposible with a westerbeke 40, paragon tranny and the walter v-drive......So, I am going to have them redo the prop...try to get a 17-12 out of it and what ever hand it is now.....
Nothing wrong with an "R" prop. That just means you need to reverse to go forward...
Put the prop on a bench with the back side of it (thrust side) facing you. If the top blade moves right to go forward, it is a right hand prop. If it moves left, it is a left hand prop.
thank you.....
I took my prop to the rehab shop and it is a right hand.....I had to replace my pedestal with an edson a while back and my shifting cable is on the left side. It pulls back to an indent notch and remains in gear...forward. It pushes forward and has to be held in reverse. If I change to a LH prop wouldn't that change my shifter positions. The holding indent would now be on the reverse gear and the forward gear would have t be held in gear? How is my thinking flawed and why is my prop a right hand....while everyone else has a LH?
The stock configuration is left hand. The prop shaft exits the hull on the starboard side of the rudder skeg. This offset to starboard is designed to offset a LH prop walking to port as it rotates. The propshaft offset and the prop walk is designed to counteract each other and the boat tracks straight under power.
Your boat must want to steer to port all of the time while in forward. In reverse you would not get any swing of the stern to the right when you hit reverse. I rely on the walk to the starboard side while docking as the boat sucks into the dock on the starboard side when in reverse.
Dale
Do you have a picture of the mounting of your shift cable at the tranny....
Please send to my email....Homeagain2008@live.com...Why is my shifter different ...if I have a RH prop....
You can buy a new Sailer 3 prop from Deep Blue Yachtsupply (see internet) for $511. Takes them 4-5 weeks to deliver. How your present set up has worked at all is beyond me....
And Dale, I am off to Tonga in ten days. Ray Deming, that angel of a man, sent me a discarded Paragon gear and right now I am busy fitting a new bearing and oil seal to the end assembly. I will bring that assembly piece with me and put it in place of my leaky one before departing for New Zealand. You will hear more from me soon Keep your fingers crossed for a good passage.
Me neither...but it moved the boat somehow...does anyone have a picture of how there shift cable is attached to the paragon tranny.....maybe that is where I need to start my investigation.
Sea Dragon has a Paragon PM10L transmission... You can see the shift linkage in the first photo on this page.

I do not know if this helps or not.

Mine shifts on teh side
Well... mine looks like this. As you can see the shift fork clevis is on the starboard side (left in this photo). Pretty straight forward.

Dale
That is what mine looks like also...when it pulls to stern..toward engine...that is foward gear....?
YES - as far as I can recall. Boat is in Tonga. OOOOPS! - Looking at the drawing of the gear box I am inclined to think NO.
Better wait for confirmation from someone who has his boat nearby.
How is that for unhelpful "advice"?
I am heading to the boat tomorrow morning to measure a forward brace for the trailer project. IF I remember I will check. Guessing, I would be inclined to say because Tonga is in the southern hemisphere, Carl's toilet flushes backward as well.
Dale
Ummm, I have a question about the Paragon. I have never been inside one. Are the forward and reverse clutches the same size? The reason I ask is that if Carl has a RH prop, he is having to run in reverse to go forward. Some of the old Twin Disc marine gears have a smaller (wimpy) clutch for reverse, the wisdom was that it would not spend much time backing. Musta looked good on paper...
Carl, I'm not trying to buy more trouble for you, just trying to prevent a repeat failure.
I have no idea why my stuff has to be different....but I have a RH prop. Standing in my cockpit....looking at the end of the motor with the pulleys....my transmission turns to the left (port) and my v-drive shaft and the propeller shaft turn to the right (starboard). It appears that my transmission has an indent to hold in forward and only pressure to keep in reverse. When I apply pressure to the transmission lever...to the bow it locks into the indent and holds...when I apply pressure to the stern direction, it has to be held to keep in reverse. Since my shaft turns to starboard and it makes the boat go forward when I push the gear to the indent direction....I do not know? Is there anyway the previous owners could have switched the transmission or v-drive direction?
I think my shaft under the boat is off set to the left...I will look today and make sure.....
I just dove the boat...my shaft comes out on the right side of the center line....looking from the stern forward
Ray, Thank you for your concern.

This discussion is NOT about my Paragon, but about the troubles of Sta - Sea - Dawn, who started the posting.
I am not the one with a RH prop and I am doing well, I believe, with my problem thanks to parts scavenged from the Paragon you sent me. The Paragon only employs the clutch plates in forward. In reverse, flipping the gear lever clamps a band around the Planetary gear and the rotation becomes right handed at the prop as long as you keep pressure on the gear lever and the band tight on the planetary gear cylinder.
Because of this mode of operation of the Paragon I think Sta-Sea-Dawn has to get a proper left handed 17x12 prop which matches the function of the gear box.
And StaSeaDawn... Don't worry too much about the Edson pedestal and cable linkage and levers. They can be easily switched to work as designed. Just get into it and you will see.
Sorry about that- I got confused over who has what.
No worries, Ray. As long as you can distinguish between your wife and your secretary you'll be fine.
Sta Sea Dawn,
FWIW:
I have a 367, Universal 5444, Hurth transmission, Walter V (RV20) drive with 2-blade RH prop.
At binnacle, move shifter fwd, boat goes fwd. move the shifter aft, boat goes in reverse. In reverse, propwalk is strong but I don't remember the direction clearly. I think propwalk in reverse is to port.
I am the only one of the owners of a 365...hull number 193...
that has a 17R10-1 1/8 prop. I have the westerbeke 40 HP ...Paragon...walter v-drive... The tranny locks into indent and goes 5 knots at 2000 rpm forward and holds in reverse and goes backward. I can control prop walk with helm. Reverses well enough for me to walk in and out of my slip single handed....I know everyone says change it...but it works.........seems to me if I change, the indent and tranny will reverse positions?
Is it possible that your propeller is mismarked? The W40 (Perkins 4-108), Paragon transmission and Walter v-drive (R10 Pearson Special) should produce in forward gear a left handed propeller (counter-clockwise) rotation when viewed from the stern. You can check this by running the engine in forward at low RPM in the slip. If the shaft from the v-drive to the propeller rotates counter-clockwise when viewed from the stern, you have a left handed system. Propellers are are usually designed for better performance going forward but this may not be obvious.
