    Water test on 115 HO etec

    propping, even if someone knows what they are doing, can be....interesting, difficult, and expensive. 🙄 I can't answer that question specifically, only by example. My new Merc. in 2021 came with a merc. 4blade - 14x14..an even pitch. I needed a 4 - 14x13, merc didn't make one...No one did that...

    Water test on 115 HO etec

    ok...so, I think rubex is correct. Jimmbo is correct. You have to test the boat in one configuration. And I'm sorry, I ass-u-me(d) ...you knew more, so I'll back up some. Your motor operating manufacturers rpm range is 5500-6000 @ WOT. Standard opinions on ventilation plate starting position is...

    Water test on 115 HO etec

    well...I finally decided to look up your motor myself and, the info that's been posted on here is not right for your motor. I should quit assuming. Your rpm range @ WOT is 5500- 6000, according to Rubex....unless THEY are wrong. So, depending on what you want, it's fine where it's at. So...

    Water test on 115 HO etec

    I'd be scared too, for my motor. You're 600 rpm above max, so I'd have to go with a 21P. Propping can be ...expensive. I'm ass-u-me ing the motor height is correct.

    Mercruiser 4.3 Prop Question

    eh, 3800 is lugging your engine. I'd be concerned with getting close to my max rpm @WOT. Then let performance be what it is. Generally speaking, a 2" change lower will get around 400 rpm's higher, still under your recommended range. and, yes, is the engine healthy?

    Cracked Engine Pod Mount

    yeah I'd have to look again but my pod is bolted to my "C" channel ribs.

    Cracked Engine Pod Mount

    in that case it looks like an age fatigue issue, which suck. I'd still use a transom saver after fixing. I was surprised at how much bounce I saw on mine without a saver.

    Water test on 115 HO etec

    I'll go out on a limb and just say HP is HP.... 1960, 1980, 2007, 2019...doesn't matter. Then I'd say what is the rpm @ WOT. If you tune for more than rated HP, you change parameters but the bottom line #'s are what count for propping purposes. See what the 15p does , go from there.

    Cracked Engine Pod Mount

    couple of questions. Is the motor original with the boat? How big is it. How old is the boat. Do you trailer it often or regularly? If so, do you use a transom saver.

    Top speed

    well, right out'a the box, there should be no water in any toon...period. First and foremost, you have to find that leak. Most common areas to leak are at the toon section seams, and the brackets attaching the toon to the deck.....I've had both. I don't have a center toon so there may be...

    opinions....

    ok....noted. Any seconds on this from others? Salt trails mean anything? There is "spidering" evident in the transom hull paint... This boat has not sold since spring......more flags ?

    opinions....

    yep...I wondered what that was.....what does it mean? and bravoitis?....They made it very clear that both manifolds had been replaced...and they were, I could see that...my common sense says, ok,but, only 300 hrs? like I said I am not outdrive knowledgeable.... That "caulking" isn't on the other...

    opinions....

    that's what it appears to be....but I'm relying on "old salts" on here as to what they think. I'm not experienced on outdrive issues, signs, or symptoms..

    opinions....

    The outdrive is a bravo 3, on an '06 sea ray. supposedly 300 hrs. Not many pics, I know but couldn't see any other areas to question. engine (5.0) compartment is very clean, well maintained....there are no grease, rust or oil stains. So , see anything ? good/bad.
