I have a question the reverse bucket doesnt look all the way up. on the rogers it does the samething.  it just seems like it is being restrictive. any adjustment.  sorry about imposing on the thread but this could you too...

Whats a safe RPM to be at? I have a 468 bbc.

I usually run mine at about 3000-3500 rpm's. I'd like the engine to last, so I don't gun it too much;D

:-\

It all depends on how the engine was built. If it was clearanced good, has a good oil pump. makes good oil pressure and you have a good oil pan and watch the temp (oil and water) running it at 4,500 all day long won't hurt it anymore than running it at 3,500 all day long.( more or less)

If you have a provision for an oil temp guage put it in and keep an eye on the oil temp. Also if you are going to run it hard use a synthetic oil.

My brother and I go from Fishers/Martinez to Pacacho (12 miles) in 14 minutes at 3,900 rpms approx 50 mph with the oil cooler 190* oil temp 140* water temp. It tips into the secondaries at 4,000.

Hope you have many happy hour's boating.

My pops had a few jet boats years ago and only one had a diverter. It should bring the good memories back.

Thank you VERY MUCH ! for that order  :) TOO Tom 

I called and asked for you, but the lady said you were out. Hopefully I still got the scjb deal.  ;D

Would you reccomend installing myself and taking it to a jet mechanic? i talked to my buddy today and said it should take 2 hrs to install it and he'll charge $160. my dad (certified automotive mechanic) said we could do it. it doesnt seem like much and im faily mechanically inclined, but i wouldnt want to ruin anything.

It was an easy install, thanks.
Will a 3 degree wedge give me a much higher roost?
I ordered it, and haven't installed it yet, due to the bolts being to short.

Heres a pic of the roost.

Taco'd "a person or people that show up with one lake lice and a family of 50 and cram 3 people at a time on it with no disregard to boating rules or ethics. Usualy crap in toilets and throw shit paper in trash cans. Hang out at the boat ramp like its a swimming hole. Have zero insurance on anything they own and dont give two shits less about your property."

we adjusted the cable, but it still has about a 20-30 degree downward nozzle. i wasnt sure if that was normal, hopefully the wedge helps out.
