Smoak352 Posted September 15, 2019 Report Share Posted September 15, 2019 I just realized I need a prop. Not sure if I want to go 3 or 4 prop but what size and pitch should I go with. I have a 300 Yamaha. Quote Link to comment Share on other sites More sharing options...
finbully Posted September 15, 2019 Report Share Posted September 15, 2019 Call PowerTech and discuss your wants with them. They have never steered me wrong. 1 Quote Link to comment Share on other sites More sharing options...
bkh Posted September 16, 2019 Report Share Posted September 16, 2019 Second on power tech, I think Marcus is still the guy to talk to but I am sure they are all good.. Tell them what your needs are (shallow water, quick hole shot, higher speed, etc.). I have a 4 blade, I think 17 pitch for my 150 hp 2200 TRS. I run pretty shallow and need a quick hole shot and dontcare about top end speed but understand others may have different needs. 1 Quote Link to comment Share on other sites More sharing options...

Bruce J Posted October 26, 2019 Report Share Posted October 26, 2019 There’s a Pathfinder Prop Discussion section in this forum - one of the “chapters” at the top of the page. Within that there is a lot of discussion about props for a 2400 with the F300. Quote Link to comment Share on other sites More sharing options...

Two people had the HS4 15X22 and one was favorable results and the other did not look favorable. I guess I will just have to bite the bullet and try a few.

Smoak352 Posted October 27, 2019 Author Report Share Posted October 27, 2019 I ran two different props today and I need a little help with the results. Both tests were done today on a 2019 2400 Pathfinder with 9 hrs. We had 3 people on board, 4 batteries, and 1/2 tank of fuel. I think the HS4 is the better prop here but I am thinking 5400 rpm is too low. What would happen if i went from a 22 to 21 pitch? The first prop is a Yamaha SWS II 15.25 x 19 (3 blade) The second Prop is a Yamaha HS4 15.00 x 22 (4 blade) The third is a Powertech OFX4 x 20 SWS II HS4. OFX4-20 RPM MPH MPH MPH 3500 34 34 32 4000 34 40 38 4500 42 47 46 5000 44 52 52 5500 51 55 (at 5400 max) - 5800 (max) 54 - 56 Quote Link to comment Share on other sites More sharing options...

Drummer Posted November 29, 2019 Report Share Posted November 29, 2019 Thanks for the great info. Are you getting the same speeds on your GPS as your Yamaha gauges? Also, how's the holeshot with the PowerTech prop? Quote Link to comment Share on other sites More sharing options...

Hole shot with both 4 blades was great but the "clunk" of the PowerTech drove me crazy. 1 Quote Link to comment Share on other sites More sharing options...
Smoak352 Posted March 23, 2020 Author Report Share Posted March 23, 2020 I have found "The prop" for the 2400 Pathfinder with a hard top and 300 Yamaha. It is the Yamaha HS4 15.00 x 21 (note I previously tried the 22 pitch of this). I tested this prop with similar weight and got great results. 55mph at 5900rpm may not be quite as good at the OFX4 that clocked 56 mph at 5800rpm, but I could not take the CLUNK when popping it into gear. The Yamaha is very soft. Quote Link to comment Share on other sites More sharing options...

The top right corner of the gauges will show "GPS" and the time when it is connected to the GPS. 1 Quote Link to comment Share on other sites More sharing options...
