I have a 1982 Evinrude 35 on a 1973 Whaler 13'. The prop is nicked up and I came across a steal on a prop the other day but don't know if it will be suitable for this setup. It's a Quicksilver 12.25" diameter x
13" pitch. I think the 13" pitch will be OK
but the prop that is on there now is more like a 10" diameter. The wordage on the website says that (among others) it is for a 1976 or newer 35hp OMC. 12" seems awfully big though. Any thoughts ?

Best prop is the 10x13" OMC. You can try it but unless it was rehubbed, I doubt that Merc will fit. I saw one on e-bay recently cheap. I tried the 10x15 on mine and it is too big.

Nick,

That was the Aluminum OMC prop, not the SS?

My 10 x13 SS OMC has never worked very well.

By the way, F15, there is quite a bit of information on how to prop this particular hull-engine combination in the archives if you care to search it out.

It seems that there were a bunch of 1982-ish 35 HP OMCs bolted onto 13-Sports.

Comprop makes a great 10x13x4, that you can find for $59.00, it works great on a 13 whaler with a 2 cyl. 35 johnrude.

I reported some test results on this engine a while back (see continuouswave.com/ubb/Forum4/HTML/000482.html .

I tried a Comprop before I put a tack on the boat, and it seemed to me to be comparable in performance to my 10x13 OMC SS--which was a real pooch at 600 ft MSL. At 5000 ft MSL, the 13 pitch SS gives me 28 MPH at 4600 rpm and the 11 pitch aluminum gives me 28 mph at 5600 rpm.

The torque curve must really be steep in the 4000 to 5000 rpm range on my 82 35 hp Johnson.

Based on Nick's comments in the past, I intend to try a 10x13 aluminum--if we ever get enough water up here to float the boat.

T....you elevation is where the difference comes in. If he is sea level(like most boaters:) the 10x13 would be great or the comp prop. I think with my 35 it would do 5500 on the nose with a light load running the 13". With the 15" it would run 5200 but add another person and she was a real dog. I assume the 10x13SS would heve been ideal in my situation but I was not in the market for a $300/prop.

Nick,

Elevation is a big factor. However, that SS prop always seemed like a dog even when I was on Lake Ray Hubbard in Rockwall, Texas.

Only one way to tell for sure. And, it gives me something to play with.
