    Rev 4 to something else

    Yeah. Interesting too I thought. Knew the rev 4 would have lots of slip, the quicker the boat is. Will have more again on your boat..and the performance it has.

    Rev 4 to something else

    Ah. Very interesting stuff there. Does she record maximum rpm achieved somewhere in there ? Like the vessel view does ? Anyway…just on the eco. There is or was something about them that I thought let the side down. Can’t think exactly what that was…but it was something mentioned or gathered...

    Rev 4 to something else

    Just read that a 19” enertia eco has a 16” diameter. I also presume that they are made from the same lightweight X7 stainless alloy material that the normal enertia is. My enertia in one hand and any other prop that ain’t x7 in the other hand…there is a considerable difference in their weight...

    Rev 4 to something else

    Ok. The Enertia eco likely comes close for diameter. Don’t know exact dimensions for them…but I know for sure they have a fairly huge diameter and design had certain boat types in mind, yours and similar likely amongst them perhaps. How easily you reckon you’re seeing the limiter as you are AD ?

    Rev 4 to something else

    I’d avoid the mirage and even the later plus version. Had their day and their place once upon a time…but certainly, there is better and much smarter props around since. You’ll know plenty already about props AD, I’m sure…but need to be careful where you go from here. It might help to tell you...

    Penta 4.3 GL in saltwater?

    Fair comment Lou. I can only really offer comment on the 89’ VP AQ205 and the ‘91 mercruiser 4.3 4 barrel I had…that I was aware for sure took around the 5l or just close to that, if a little under. Always required a 5l tub of oil…or frustratingly (if keeping oem on the mercruiser), the 4l tub...

    Off-Season Float Battery Charging, 2 Batteries

    Hi. Very common here for most boats to have a marine multi output charger installed. Anything from 2 to half a dozen separate outputs. Proper way to go about it. Be likely not an ideal arrangement to have a charger with one output, trying to charge two different batteries. They will almost...

    Penta 4.3 GL in saltwater?

    If it helps…most of the gm 4.3’s will take around 5l of oil or close to either side. Including filter and getting to the required level. Had a few 4.3’s in boats one after the other..then went to a 5.0 mpi just after. Was taken back by the 5.0 taking less oil than the 4.3. By a fair amount too.

    Please somebody indentify my boat

    Yeah. Definitely nothing like one eh. Nice looking paint job there.

    Mercruiser 5.0 starting problem

    Is this an mpi or carb ? If it’s an mpi I’d be thinking battery for the first behaviour. When it’s not doing anything at all..either as above or the relay on top of the engine is bad…or you have a dodgy connection at the battery or battery isolator

    Mariner 2 hp .

    Thanks. Hopefully she won’t need too much persuasion

    Mariner 2 hp .

    Excellent news. I just picked myself up a ‘88 Yamaha 2b, non running. I’m blaming you for this, haha. Always wanted one. Just got her running today. Cleaned up the points and brushes…new plug and fuel…stop switch was showing a circuit when it shouldn’t, from corrosion in there. Sorted that..carb...

    Looking at 8hp and 15hp 4stroke Merc

    I can steer my boat with the main engine, when the auxiliary engine is powering the boat. But only if the auxiliary is adjusted and friction set at a steering angle that’s a little offset, to counter the side it’s on and it’s affect. Only in open water though. Wouldn’t be any use in close...

    1999 Mercury 40 hp 2 stroke Overheat

    Sure it’s not a low oil alarm ?
  15. Q

    Water in the powerhead

    Hi. If your engine is anything like my 2016 merc, that has the oil drain fitting that’s located about the mid section of the thing..are you sure it’s not maybe that you’ve had water from that ? They are just about or sometimes on the waterline.

    This shaft is too long, right?

    Looks like a short shaft, I’d say. Transom looks like it’s less than usual dimensions. Measure your transom. If it’s less than about 17”…it’s as above.

    Please somebody indentify my boat

    Not sure she’s a hydrostream, but a pic from the rear or of the rear underside of hull would give it away, if she was. Very distinctive around there. Wish to god, I could find one this side of the Atlantic. Dream boat for me.

    330 black scorpion low power

    Was that a wee dig at me ? Not sure I get you, if so. Typing on phone, as usual.

    330 black scorpion low power

    A good call Scott and crossed my mind too. But the mention of being sluggish before those rpms too…made me think otherwise. Can’t remember if it’s 2500 or 3000 rpm the neutral switch would cause. Only happens on some mpi from about at least the mid 2000’s onwards too, as most will know. My 2003...

    Replacement Prop Selection

    Get the drive ratio stamped on it and the prop pitch. Go from there. Your figures suggest your prop is way over pitched. A typical example of a boat like this with that set up might have a drive ratio of about 1.47-1 and say a 17-19” prop. 19” would be on the tall side of pitch with that ratio...
