Hello All, I am new to this forum but have an old hat at boating. However this is my first Jet Boat. I grew up on the lake and can remember when my dad had his 18' Flat bottom 455 olds jet, (dont remember what hull), but i have wanted one ever sense. I now have a 1979 Sunkisst 18' 460 berkely pump, jetovator. I just got it friday and LOVE it... Guy told me it was a 70+ mph boat, but as typical bragging goes, he was wrong. GPS today showed 62 at 5200 rpm. now to the questions.
I realize that the easiest way to equate speed is RPM.
1, I am looking to target about 75 mph if possible, Does anyone know if the 79 sunkisst hull is capable of 75?
2, it does not have a scoop intake but it picks up water great, does the drag you create by adding the scoop intake outway the gains, or are the gains worth it?
3, is there an increase in top speed with a droop snoot , and what are the negatives
4, ride plate , Pros and cons???
5, Last but not least, I own a macine shop and we build performance engines for cars, I am wanting to build a roller cam, roller rocker, 7000 rpm 460. question is what rpm can the Berkeley Pump handle and what rpm do i have to start worrying about blow out? also will blow out be a problem if i do the intake scoop i asked about earlier?
ANY AND ALL OPINOINS APPRECIATED.
I know not all of you want to answer, but if you have .02 i want to hear it and will consider it all before deciding, i plan to post my decisions and share the results with you all.
Thanks to you all in advance,
George from Georgia with his new toy!!!!
