    E35-2 Prop Replacement Question

    Hi, all. I recently bought an Ericson 35-2 and joined this group. The zinc on the prop shaft had fallen off so replacing a corroded 13" three-bladed, fixed prop is a priority. The boat was repowered with a Yanmar 3GM30F and the shaft is 3/4". Anyone have experience with this configuration and...

    Prop Puller in Nothern NJ or Southern NY

    Does any one in either the Northern NJ or Southern NY area have a prop puller that they would lend/rent? I finally convinced the captain to go for the Indigo Prop (gee I really miss the excitement of backing out of the slip). Now we just need to persuade the old egg beater to relinquish it's...

    Installing Indigo Prop

    I just received an Indigo 3 blade prop I ordered for my E27 with Atomic 4. The good comments from owners on this forum made me decide to try it. :) I noticed the instructions recommend using some valve grinding compound when installing it to get a good fit between the hole in the prop and...

    Correct or Ideal Prop for E29 w/Atomic 4?

    I recently purchased a 1971 E29 and am in the process of bringing her back to life. Just finished installing a rebuilt Atomic 4 and now need to replace the existing prop (an old 2 blade). Are there any suggestions on how I determine ideal prop size, pitch & 2 or 3 blade? I've heard that stock...

    Wanted Martec Prop

    Been watching Ebay without much luck, so I thought I'd try here. I'm looking for a used Martec folding prop. Martec suggests a 15 X 14 X 1 RH. I find 16 mostly on Ebay. This is for a E34 Thanks, Paul

    Overpitched Maxprop

    Last time we went sailing, I could not get the engine (Yanmar 3JH2E) past 1,800 rpm, so i suspect the Maxprop is overpitched. Based on the engine's user manual, maximum HP should be around 3,400-3,600 rpm. Does anybody knows if adjusting the pitch on one of these props can be done underwater...

    PYI Flexible Coupling & Prop Overhang?

    I was just about ready to install a PYI 910001 Flexible Coupling on the M-25 in our E32-3 and started reading the posts on this site. I am just not sure about sliding the shaft back another 1.28 inches. I would still have enough room to repack the stuffing box but having the prop back furthur...

    Prop size calculator

    Is anyone aware of any links with a calculator to figure the proper prop size for a given boat and engine. In my case I have an E-27 with a Yanmar YSB-8 and no tachometer. How do I calculate for the best efficiency of a given prop size, pitch, and number of blades?:confused:

    3 Blade Fixed Prop FS

    1 inch shaft bore, 16 X 12 RH prop. This was on my E-38. Correct pitch for this boat should be closer to 16 X 10.5 or 11, but this prop could be repitched. I am using a 2 blade fixed prop now and am in the process of getting a feathering prop. I can ship this guy at your expense. Its in fine...

    Ericson 30-1 prop alignment

    When I first got my Ericson last month I wrote asking about the underbody of the boat ( I haven't seen mine out of the water and I know it has rudder damage) and was given some very good information--to contact Bruce King for the line drawings. This I did and received them. My question is has...

    E-34 Universal 25XP - RH prop recommendation

    The 2 blade factory fixed prop just is not pushing my boat through strong chop and current, where it cavitates and the boat looses steerage due to no forward speed over rudder. I looked into a Maxprop 3 blade feathering and the shop recommended 15" diameter, 9'' pitch, 1'' shaft. The cost to buy...
