i have a 1996 johnson 200 venom and i was wonderin what the rpm range for this motor is. had her out gettin some readings at wot
30 psi h2o at wot
5400 rpm wot with a 24" raker
61.6 was the best speed i could get with the 1996 jave 400 sdc
dont know what the prop to pad is im gonna get it tonight
anyone have any ideas?
i would really appriciate it
thanks, luke
I would think with that kind of PSI you could jack that up a little bit more and get the RPM's up. With that your pressure will come down, R's go up and hopefully MPH as well. PSI/RPM's seem about right with it being as it is. I would think 5600-5800 and around 18-20lb's PSI would be about perfect and it seems by your numbers that it is attainable. Raise that up until your MPH go down as you have plenty of room to move.

i also forgot to ad that the prop that is on it now is banged up pretty good some of the cup has been beat out of it from the previous owner
24 rakers are pretty easy to find. There's one in the prop4sale forum for $200. Check out e-bay too. You need a good prop for the best performance. If it's really beat up, it can cause a lot of vibration in the lower unit and screw up seals, bearings, and gears.

just the outside is beat up looks like a lot of the cup was lost because of it
dosent viberate or anything
thinkin im prob gonna go with a gade just dont know if i should go with a 23" or a 25"
this is the first time that i have ever done anything like this with a boat like this so i dont really know much about it
I'd go w/ the 25 gade if your going to get a gade. If you don't have a jackplate, I'd suggest getting one. I run a 24 raker on mine and it runs about 3-4 mph more than the 25 gade. The gade is my spare. Hole shot is better w/ the gade though.

Well if you go with the 23" Gade you will see an increase in your RPM's but about the same MPH if you just swap those props out. I would still jack up that motor a bit before you do anything to get the RPM's up then change out props. That way your not chasing your tail if it's the motor or prop that's not getting the RPM's up. Up that motor a 1/2" and see what you get and then let us know, but I wouldn't do anything until then.

i have a 6" rite hite jack plate on it now but i will have to look tonight to see where the prop is in relation to the pad.
was gonna do it last night and got busy puttin pro trim and the hot foot in
I had the evinrude 200 vindicator, same motor as the johnson venom I believe. I was real down on the motor, got about the same results you have now. I raised the motor until water pressure dropped the lowered it a quarter inch. Still only got about 63 mph at about 5800 rpms. I just bought the evinrude E-Tech 200 HO and ran 70 (gps) with the same prop. So personally, I hope you get more but I don't think you will from your venom. Good luck!

man i hope i can get more out of it than that
that will be very not cool if i cant
Make sure you get the Renegade thrust washer, its smaller than the Raker.
You may want to get a blow out ring also.
not really sure i know what you mean by a "blowout ring" rusty?
The hub on the Renegade is smaller than the Raker, there is a plastic ring (blow out ring) that clips into the gearcase to take up some of the room, it keeps the prop from blowing out when planning the boat.
Part number 126669 @ $8.29.
I blow out ring sits inside the gear case and is usually made of plastic (black). It prevents exhaust from coming out of the side of the prop on the Renegades. If you do not use this on that prop your prop will blow out and it will take a long time to get on plane as the exhaust will go over the prop opposed to through the prop. You can get one from your dealer.

Rusty, guess I was typing the same time you were, just posted a little later. Darn phone.

with the rpms that i have do you think that the motor will turn a 25 gade good enough
prop is 4-1/4 below pad.
someone also said a tempest prop as well.
any other opinions or ideas?
23 gade tuned up to a 24.........
You should be able to spin a 25 Gade around the same RPM's.
what would a tempest do rusty?
or should i stick with the gade?
and what should me h2o psi be at wot rusty and the rpm range as well 5600-5800?
5000 to 5500 Rpm's, water pressure 15 PSI at WOT, as for the "other company's props" I would ask Todd on the set up boards.
