Baller 6balls Posted January 18, 2022 Baller Share Posted January 18, 2022 Is there a really good prop shop that can listen to what is going on with a particular boat, hear about what prop is on there, then make some recommendations? My nephew feels like his carb-powered Sport Nautique is anemic on power but the motor should have plenty. Not sure what prop on there currently but I'm sure he can get that info. Anyplace I should steer him for good recommendations on a change to enliven his boat? THX Link to comment Share on other sites More sharing options...

Baller_ Mastercrafter Posted January 18, 2022 Baller_ Share Posted January 18, 2022 I'm an OJ props fan, you can call or email Eric, the owner, and he'll do exactly what you're asking. Of course, need to know what's on there now. A new CNC prop can really make old boats come alive. If the boat suddenly started to feel anemic, I'd check compression, ignition timing, perhaps manifold vacuum at idle, and so on, as something could have gone south.

Baller ALPJr Posted January 18, 2022 Baller Share Posted January 18, 2022 ++ for Eric at OJ. Could the power issue be caused by a slipping transmission? Link to comment Share on other sites More sharing options...
Baller Dano Posted January 18, 2022 Baller Share Posted January 18, 2022 OJ props. I upgraded to a new CNC Eric recommended and it was a huge improvement. Agree with @Mastercrafter he should check those items first. I would suspect ignition parts either worn out or dirty/corroded. Spark plugs are a wear item. If they are old they can be working seemingly ok at idle but providing weak or miss fire at RPM's. If he does a spark test and sees anything other than a crisp blue spark at the spark plug, there is an issue with the ignition. Link to comment Share on other sites More sharing options...
Baller 6balls Posted January 18, 2022 Author Baller Share Posted January 18, 2022 I think it has a pretty recent, fresh tune-up but will check with him. Actually will link him this post later today thanks for the advice thus far and any in the future. He runs buoys at a club, but has an open bow sport nautique with a tower for the family on the big lake. Link to comment Share on other sites More sharing options...
Baller 75Tique Posted January 19, 2022 Baller Share Posted January 19, 2022 Go over to, or have your friend go over to CorrectCraftFan. There is a member there "TRBenj" who is a prop whiz. Has access to a gazillion different boats and a gazillion different props and has done a million trial and errors with various boats and props and knows a lot about what subtle changes will have what results and what props are best for what boats based on desired performance.

Baller ski6jones Posted January 19, 2022 Baller Share Posted January 19, 2022 I wouldn't buy anything from TRBenj (referenced above). I bought a Nautique muffler from him and it was in worse shape than the one I had. Of course most of the cost was shipping, so the damage was done. Just a word of warning, I don't trust that guy.

Baller morfoot Posted January 20, 2022 Baller Share Posted January 20, 2022 Sorry you had a bad experience with TRBenj in purchasing a used item. I'm friends with the guy and it seems unlike him to do a fellow Nauti owner bad. He's a motorhead, has a Barefooter than he's restrung using composite naterials dropped a big bored motor in it that'll do mid 60's on the water. Back on topic he is the prop Guru when it comes to Nautiques and probably other brands and the first guy I'd call or recommend to someone looking to upgrade their prop. As mentioned above by 75Tique. TRBenj KNOWS props. @6balls ...what year is your nephews Sport Nautique. My guess is that its got a 1:23 Tranny and a ACME 422 might be the prop for that boat BUT I'd search Planet Nautique or CCFan for a definate answer or response.

Baller 6balls Posted January 20, 2022 Author Baller Share Posted January 20, 2022 @morfoot I think circa 2000 off the top of my head. Link to comment Share on other sites More sharing options...
