fishbonejrs prop problem
 

i really am not sure how to tell what size prop i have so i am puttin down every thing i saw on the prop. i think it is too big and that is why i dont get over 4000 rpm at WOT.

here is the first code

48,78,122,a40,

this i think is the picth (P21)

this is the other thing i saw on it

THORELL R7199

not sure what this is but i need help with it

thanks fishbonejr :)

Re: fishbonejrs prop problem
 

looks like a rebuilders code, check with your local proshops, maybe someone can decode it, or at least put the prop on the pitch blocks and tell you what the pitch is( probably more accurate than going by whats stamped on it)

Re: fishbonejrs prop problem
 

He is right....go see a good prop guy. Thats the best way without any doubts. ;)

Re: fishbonejrs prop problem
 

ok so the prop is rebuilt not new. i think that it is not the right prop for my engine anyway. i think its two big i went to a little smaller engine when i replaced it and get about 700-800 rpm less than i used to.

Windtalkers were American Indians in WWII that would speak in native tongue
to communicate secret messages.
The enemies could not decifer what they were saying.

There was a movie a few years ago about this subject.

Re: fishbonejrs prop problem
 

yup it sure is.

but i have another question i have a remanufactured engine from JASPER i don't know the reccommeded RPM'S and i dont know the reccommended prop for the engine should i e-mail them about this or does anybody know. the engine is a 3.7 liter 125 horse power inline 4.

Re: fishbonejrs prop problem
 

you should call them and see what they say.

But I hope you DON"T have a need for speed!! That thing is going to be a dog!!

I know I had the 165 inline and it was rated 120hp, and I was lucky to do over 30 with a good tail wind.

Re: fishbonejrs prop problem
 

the engine is SLOW and it makes me very angry >:( >:( >:( >:( >:(. i cant pass sombody i want to because i dont get more than 25 knots WOT G.P.S. and it will never get on plane with more than four people onboard.

also check the thred "will this work" for your answer on the need for speed thing.

Re: fishbonejrs prop problem
 

CAPT. Bent and Charlie have I/O's, see what prop they are going with.

Re: fishbonejrs prop problem
 

i am a captian now what an honor ;D

yo charlie what prop you spinning

Re: fishbonejrs prop problem
 

the 3.7 liter should be rated at 165, 170, 185, or 190 depending on what year model you have. The 2.5 was rated at 120, the 3.0 was rated at 115( late model, measured at the prop) 130, and 140 depending on what year. The 3.0 LX was rated at 135( late model rated at prop). All these engines are rated to turn between 4400 and 4800 at WOT, light load. If your engine has a heat exchanger, closed cooling system, and if the instake manifold is on the oposite side of the exhaust, you have the 3.7. A lot of people give this engine a bad rep, I have had good luck with them. IF the carb is mounted on the exhaust manifold, its the 2.5 or 3.0, its a good engine but its only going to do so much. What engine do you have?

Re: fishbonejrs prop problem
 

i know it is a 3.7 because that is what is has written on te engine check my gallery there are pictures of it there. fishbonejr

Re: fishbonejrs prop problem
 

did you ever find out what pitch and diameter it was? Take it to a propshop and get them to check it

Re: fishbonejrs prop problem
 

no havent had time yet i might this week though.

Re: fishbonejrs prop problem
 

Not really, in the words of the chinese guy in the tea commercial,

"you can find dis stuff on da internet"

Re: fishbonejrs prop problem
 

i looked at your gallery, your engine is a 165 hp, pretty good version of that engine, I'm not a fan of that mercrab on there, but replacing it with a two barrel Rochester takes some modifications. You might start looking for a used 4 barrel set up for that engine, they are hard to find, but it couldn't hurt, it raises the hp to 190, had the same bottoom end and cam, only differrence is the intake, carb, oil cooler. try to get it all as a package so you'll have everything. You may have to replace your throttle cable also, as it comes in at a different angle. Another good thing to do to that engine is to replace the points with an electronic ignition, use the "pertronic" conversion, it uses your existing distributor and is easy to install, its also available thru Sierra. There are several things that can be done to that engine, but remeber, its still a 4 cylinder, it will never run with a 5.7.

First and formost, find out what prop you have! Then go from there.
