Hi everyone,
1988 Gambler 183 with a fresh rebuilt 1989 Mariner Mag II 150, has everything done to it you can do except for the 200 front half. Motor is built to turn 7000 rpm although don’t plan on doing that regularly. Currently running a Turbo 23p 4 blade (came with boat) which has been a surprisingly good prop. Still have a couple hours of break in left but know I can spin it to 7000 (only done very briefly so far). When accelerating from 6000 to 6500 hit 65.8mph and boat was pulling pretty hard still. Water PSI is 15+, not sure on prop to pad as I’m running a 10” Bobs hydraulic so adjust on the fly but sweet spot seems to be around 3” below which is lower than I expected but that’s where it likes it. Lower is the bigger bullet case with 1.87 gears.
Was planning on waiting until break in was over before trying some different props, specifically Tempest and Trophy, but came across a really nice 25p Tempest A45 for a couple hundred bucks, seller won’t ship and the round trip to get it would be 4 hours. So before I make that drive was hoping to get some input on if you prop guys thought it might be a good prop for the boat. Even if it’s close, I would send it to Mark to be balanced and blueprinted so could have it tweaked as needed, just don’t want to make that drive if definitely not a good choice.
Thanks!
Willie
