SCFD rtrd. Posted September 28, 2016 Report Share Posted September 28, 2016 Have you tried the prop used in the performance test? They say, " T-top, 1/2 tank fuel and two persons" = 63.7 mph. I'd like to try this prop, but the cost is $1,000. Link to comment Share on other sites More sharing options...
Laid Back Posted March 18, 2017 Report Share Posted March 18, 2017 I have the prop listed in the bulletin. I have seen 65, down wind / down current, but I can hit 60 with 2 people and full fuel with fishing load no problem. No t top, but four batteries and a trolling motor.

I have the same boat (2014) and motor and ordered a 15X23 blade with part # 6BR-45B74-00-00 which was on Yamaha's 1/4/11 Performance Bulletin for the same engine and boat.....which max at 6050 rpm and 63 mph. I have not been able to get over 5100 rpms or 50 miles per hour on mine....boat empty and single person. I'm concerned about using another manufacturer while under warranty...6 years. I had the same problem with my 2005 pathfinder with a 150 F until I went to powertech. Link to comment Share on other sites More sharing options...
JEM Posted March 23, 2017 Report Share Posted March 23, 2017 Wow! That is pretty bad! Same prop... 6050 rpm's and 5100 rpm's! I wouldn't hesitate to go with a different prop. As long as you get your rpm's up, I don't think the prop would affect your warranty. If anything, that Yamaha prop is killing your engine! Link to comment Share on other sites More sharing options...
Moderator Posted March 23, 2017 Report Share Posted March 23, 2017 Charles, You need to have a competent person take a look at your boat.. Something needs to be changed. I looked up the part and you have a 4 blade 23 pitch prop.. Same as Performance Bulletin.. Scratchin my head.. Maybe a local Member can loan you a 3 blade 23 to try.. Your boat should F L Y .. Where are you located, Charles ? Mod -1 Link to comment Share on other sites More sharing options...

Moderator Posted March 25, 2017 Report Share Posted March 25, 2017 Did you buy the HPS at Caribee ? If so, They may be able to help. There could be a number of reasons.. I have heard of this when the motor is hung too low on the jack plate. A good Yamaha shop may be able to diagnose. Anybody in the Keys have a 3 blade SWS 23 he can borrow ??

ChrisB Posted March 28, 2017 Report Share Posted March 28, 2017 Make sure tabs are all the way up jack plate on 3 and trim 2/3 to 3/4. If this does not get you close to 60 or over in a light boat you have fuel or mechanical issues. If you are jacked up and trimmed out still getting only 5100 run a compression test, put in new plugs, check coils for spark, and have the fuel pressure checked under load Link to comment Share on other sites More sharing options...
geeviam Posted March 28, 2017 Report Share Posted March 28, 2017 Like ChrisB said, the engine could be starved for fuel. If the fuel tank was overfilled at the pump, it's possible that the carbon canister on the overboard vent line became flooded with gas and saturated the charcoal pellets - causing air flow restriction. It happened on my boat and had to be fixed. Engine performance was restored when the fuel system could breathe better again. Link to comment Share on other sites More sharing options...
Redneck Biologist Posted March 29, 2017 Report Share Posted March 29, 2017 You may want to try a Mercury Bravo 1 FS in a 23 pitch..... Link to comment Share on other sites More sharing options...
JD's HPS Posted April 23, 2017 Report Share Posted April 23, 2017 Charles, have a competent prop shop make sure the pitch is what is stamped on the prop and balaced correctly. My Rev 4 was stamped as a 23P and was actually a 24P. Rich Junker pitched it back and did a back cut and saw 500 more RPM'S. Prior 5400, now 5900. With the 4 blade, you should be abe to jack up to 4 and trim and those RPM'S gotta come up. 2 things, prop issue or as mentioned, diagnose the engine. Good luck...

OlivierHPS2300 Posted April 23, 2017 Report Share Posted April 23, 2017 i run a 4 blade prop and with 2 people, fishing gear and half tank of gas hit 64MPH.... Something is not working right with your set up, Link to comment Share on other sites More sharing options...
