over prop exhaust v thru prop exhaust on 60hp evinrude

[Ron Hill]

We used to shift our 235's in Mod VP, BUT as I recall, we idled them down, and we also made sure they were ALL THE WAY in gear.

I think the Tohatsu gearcase must be the best, my kids, and plenty of other used to drop those Tohatsu's in gear and everything would just go "CLUNK", but they kept running. I've seen the same in Sport C hundreds of times.

I wish we had started my COR motor in gear last summer...The throttle stuck wide open and we hit a quick 10 grand.....We put the throttle spring back on, then it made three laps before the rod let go and wiped out my entire powerhead!

I as well, but didn't those choppers and cleavers all have rubber hubs?

If a prop is cheap, buy it! If it don't work well sell it! You might loose the shipping cost and then some but chances are you will learn a lot from testing a lot of props. high speed will always cost a lot be it in money or time, most often both

So buy both the cleaver and the michigan 12x23 do some serious testing and report your findings here...

I'm sure Ron have some very nice props for your rig, maybe you need to add a prop to your wishlist for x-mas

Its funny you say that PER.
I sent a letter to father christmas earlier today asking for a nice 3 blade prop and a jack plate.
I mentioned that i understand about the big reccession and cut back's so a manual jack plate will be fine.
Also a good secondhand prop is fine as long as no major bends or chunks missing ....
i bet he dont turn up with them..

on the michigan prop im not so sure if it is 13splines now....
this is the add for it.

Gale? Better be sure it doesn't use a shear pin!

[Per]

If it is for a Archimedes Penta 600 Or rather a Volvo Penta 600 with thru hub ex it will be a 13 spline.

Joe posted while I was typing, maybe you should get a pic of it...
The facts in my previous post is still valid though

[phillnjack]

yeah i thought the same about the volvo penta
i had a 60hp volvo penta back a long time ago, very powerfull engine in its day, and that was 13 spline.
it was 1979 engine,one of thosethat came back from kuwait.
(kuwait had thousands of them when volvo were looking at stopping production, kuwait had so many just sitting in containers, lots of them came back to uk as new crated engines in the early 1990's )

and the gale bit did make me wonder a bit about the prop. i had a gale 25hp once...not bad in the early 70's..

the pic ive seen of the michigan shows it to be a 15 spline i think, not good pic at all,bad angle etc, but i will ask for a better pic of the prop.

[phillnjack]

After talking to a few people the michigan is not for me.
But since i wrote on this top ic o got another 2 props at pretty good prices.
1st is a omc alloy 12 x 23 thru hub,brand new never used prop for crazy low price.
and then i saw a prop i just had to have, its a 13.3/4 x 23 pitch omc stainless over hub silver streak.
this prop although over hub has a rubber bushing,so might be a bit gentler on the gear box.

Both props i got for good price and if they dont work ,then atleast they look nice above the work bench ha ha


after looking at them i tried them on the engine for fit etc.
i think they both look fine
