    Speed Plateaus at 5200rpm

    Speed Plateaus at 5200rpm

    well, max manufacturer engine rpm is 6200, you say...every engine has a max throttle operating range ....so I'll take a guess that min rpm at max throttle is around 5200 (my 2021 merc is 5000-6000 at max throttle). So operating range wise, your not lugging the engine with max throttle and 5800...

    Propeller

    like everyone is saying...what is the max rpm now? On my 24' twin tube pontoon with my new 115 ct merc,, they put a 4 blade 14x14 on it...max rpm was 5800 but with teen age tubers and others on board, especially when turning....My rpm's would drop to 5200+/-.... So, I stuck a 3 blade, 16x12 on...

    Upgrading from 70hp to 90hp

    FWIW... When I replaced my Merc 60 hp 4 stroke with a 115hp 4 stoke on my 24' pontoon ( which the placard said is max) ...it was noticeable. The pontoon has 25" diameter toons also..... The bigger issue was the bounce at the transom when trailering....significantly so that I now use a transom...
