New Prop

TomSG · 29 August 2011, 22:27

I have a 75 etec and was looking to get a new stainless prop for it. We use it for waterskiing and general cruising/fishing so ideally one that could cater for everything. What pitch/make would be the best?

Thanks

I would drop Julie at Steel Developments - New Propellers & Propeller Repairs - UK Wide Delivery _ New propellers available from stock & prop repairs in very quick lead times a email as she has helped me & knows her props!

Also, give Mike Vincent at South Coast Marine in Christchurch a call, Evinrude main agent & knows his props. He might, let you try before you buy if you're nice to him

You can't get a prop for everything. But if you keep a spare on board, it might pay to have two different pitches, one for watersking/rough weather/heavy payloads and one for lighter running/good weather/cruising.

What size prop are you using now, what is your WOT revs and are you in the recommended manufacturers WOT rev range?

thanks for the replies guys, will give those people a call. In terms of specifics relating to the engine I don't really have any idea as it's located in Ireland so am not able to test... We currently use the propeller that was supplied when we bought the boat and it does everything for us. I think when waterskiing it maxes out at about 4000rpm with me on the back (16 stone). Most of the cruising done is usually in rough conditions and with heavy loads so I'll probably go down that route..

you need to be seeing 5000-5200rpm at wot with your normal load with that engine.

Ok, I think I'm going to go with a 15inch pitch? Most of the use of the boat is towing skiers/inflatables and so I won't mind the top end speed being lost really.

If that's your normal load, skiers, ringos etc. you still need to be seeing 5000rpm at wot regardless of top speed.
