I've been around jets and I/O's my entire life, but this is first running one that I've owned. 73 Spectra 20, 454 and 12jc.
It runs really well, I picked it up not to go fast but to hall the family around. That being said I want just a little bit more.
The background I was given from the original owner of boat:
15yrs ago pump rebuilt stainless impellor (confirmed) unknown cut
5yrs ago flat'nd cam complete top end rebuilt (no specs)
last year motor rebuilt compression droped from 12:1 down to 10:1
motor has a nice single plane weiand and the original 780 holley vac sec.
Unfortunatly, even though the boat cam with a nice little folder with the original sales brochure, reciept and some other really cool history kinda stuff. I have no actual data on the motor specs or cam specs.
The boat gets out of the hole pretty good for its size, but tops out at only 4500rpm ( i keep forgeting the GPS to get MPH ) and cruises really nicely at around 33-3500rpm. Are there any little tricks to squeazing out a few more rpms, I'd really like to pick up the pace just a bit.
*before its brought up, I've been pouring over new and old threads (heavy search button) but all i see is put more money into it. I know there's got to be some jet boat tricks out there.
