had a prop built several months ago & never got around to trying it out. it's been laying on a shelf and i can never remember to put in de boat. had a buddy call dis afternoon to tell me he was stuck and needed a hand. so i decided to go ahead and put it on for chits and giggles, DAMN! shoulda tried it a long time ago! got a speed of 41.6MPH @ 4750 rpms! guess my old dog learned a new trick

Who da hell built that prop?

dat's de one

Those hopkins props aren't holding up to good. My "SECOND" new one will be here today!

hey coon do u hav tha part # from ur trans cooler?

Do yall think a larger oil cooler is needed for a motor with .065 decked heads, mikuni, modified intake, and exhaust?

kinda what I thought, but that thing looks retarded strapped on top of the fan. But I guess you would look even dumber sittin out on the water with a f'up motor.

Running a oil cooler on a stage 1 engine isn't necessary. The guys that have them installed on their engines do so mostly for looks.

Per Marty's post on the subject after taking a temp reading. Cooler/Kooler has got to be better..............

Stock cooler 225-230*
Aftermarket 210*
Both 195*

dis is the 5th time de stock push rods have saved my azZ
128 hrs and counting

And at $8 a pair you can afford to change em out as often as necessary.
If sumthin's gotta give it's good to know dat it's easy to fix on da water and it ain't gonna break da bank.

What is a safe operating temp for these motors? Anyone using an oil temp gauge?

When would you say the extra cooler is a necessity? I'll be running slightly modded heads, roller rockers, longer push rods, oversized valves, modded stock carb, cam, and exhaust. I was planning on adding an extra cooler, but don't have an awesome spot to put one on a vertical motor. I'm afraid I'll tear it off if I mount it to the fan shroud.

It's really not an necessity, I was just giving Craig a hard time.

It's defiantly a plus to have one, more oil capacity = lower oil temps = more life out of your motor = better for the long term on the engine, however the average person won't put enough hours on their motor to even justify it.

But it looks kool............

Congrats Man- A lot of work into that Baby!

Were increasing the air flow on these engines to nearly double overstock just by removing the mesh grass guard. Which imo deems the over sized cooler unnecessary, but...... it does incease oil capasity (a little) which isn't a bad thing. I personally think the oil cooler looks like a big ass snake took a big ass shit on top the motor!

For a few dollars and the possibility of keeping you motor 35* or more cooler it can't hurt. Don't know if Marty's temp readings were just normal running but I can only imagine how high the temps can get when your grinding your way through the thick stuff. I know mine has gotten way to hot for my liking a few times...

Looking good my boy! Wheres your pre filter!

pre filter,he don't need no stinking pre filter

I took it off to pull the filter to look inside the carb. Had a little fuel coming out the carb or so I though. Still learing about this thing.
