    Evinrude 60hp - 3 Blade vs 4 Blade Prop Pitch

    a 60 hp motor on a 16' boat needs a different prop than the same motor on a 24' boat...I know for a fact. A prop ad that says it will fit a motor doesn't mean that's the prop you need for that motor on your boat. But that's the message I got from you posting that ad...... I believe you know your...

    Evinrude 60hp - 3 Blade vs 4 Blade Prop Pitch

    "I decided to buy a new stainless prop and went from the original 3 blade aluminum to a 4 blade." # of blades, diameter of prop, pitch of prop, cupped prop or not, all affect rpm. Not just # of blades.

    New prop for my boat

    jeez... most assuredly it can..........I hope you don't find more "stuff".... I haven't had to pressure test my toons....so far all I have to do is loosen the plugs especially on a hot day and listen for expanded air to escape.....or the opposite on a colder day.....I did have a seam leak...

    New prop for my boat

    BTW...The gearcase on my '21 merc. 115 CT is a bigger diameter than a standard gearcase of the same hp......the prop has to be for that gearcase... there's also a white, plastic ring insert to prevent ventilation from exhaust gases inside that gearcase that is susceptible to breaking and going...

    New prop for my boat

    my merc is rated for 5-6000 rpm....the rev limiter is set for rpm's after 6000, before it gets to redline or a never exceed rpm....Like any engine.... It doesn't start kicking in until after I exceed 6100... Why would any engine maker rev limit his engine under the normal operating range as...

    New prop for my boat

    ok...you have more issues to fix.....I can see 2mph increase...your prop is damaged....... understand that pontoons usually come in 3 separate sections ....each should have a plug.....mine are plastic and mounted at the top..... It doesn't take much water to add significant weight...... I can...

    New prop for my boat

    at 5800, he's not severely underpropped, he's slightly overpropped....so if he gets his 6000, or a little higher at max throttle by dropping 1inch pitch, or 1 inch diameter, or dropping one blade.......then he may be able to pull a tub'er faster.....but I'll almost...that's almost...bet his...

    New prop for my boat

    um...is that prop kinda beat up?....it looks like some of the edges are . Without being there, I can't tell....it does look like the edges can be cleaned up using a file and sandpaper.....something you can do yourself......yep, it can make a difference..... I'd say the motor is too low. I...

    Overpowered 20ft pontoon.

    honestly?...depends on the kinda person you are.... after learning about pontoons, ratings, capacities, etc., I'd not want an overpowered pontoon. But I'm a mostly manual following type..... I wouldn't buy a used pontoon that had been overpowered......

    1997 fisher freedom 200dxl 20’

    well...if the capacity plate is like mine.....the 1450 or 10 is for people.. engine capacity is for the transom which has weight and HP limits...exceeding limits doesn't mean the transom will fail tomorrow, it just means it can cause issues later......you say the motor weights are close, so are...

    New prop for my boat

    those pictures above are correct ..for a planing type hull...but the problem you ...and I ...have/had is that we are dealing with a pontoon boat....not a planing hull or flat type...or even a V hull.....so it gets...complicated to a newbie...and tough to explain on a forum.....they do illustrate...

    New prop for my boat

    I had an '05 merc. 60 hp, 4 stroke big foot on my 24' pontoon... rpm range was 5-6000....the rev limiter kicked in at around 6100+ ....I'm sure yours is the same......but regarding your question.... you can't have both...it's a compromise..... props aren't magical. You're already close to max...
