    Advantages (differences) in I/O and inboard

    As said. Outdrive are more efficient usually. Easier option if space is an issue. shaft inboards are less hassle and also a whole lot more of a pleasure to handle. So much more manoeuvring ability. Outdrive also can be lifted for shallow water approach etc.

    Bayliner contessa 28 feet Volvo penta V8 5.7 L 1984

    I can’t quite be sure, but memory is telling me if it’s an AQ225...they may be 5.0l engine. Won’t be anything like 350hp. Think the 5.0 was 225hp and there is certainly an AQ271 5.7 I’m very familiar with too. About 270hp or 260 at prop perhaps. Can’t be sure. Your outdrives I think are 280...

    Mariner / Yamaha,..are they the same?

    Hi. If it helps. The 9.9 is the same unit. Your year is right on the change over for the most part I’d think. But it’s a Yammy

    Volvo penta 5.0 OSI current drain

    Hi. If this engine has any domestic ancillary wired to the battery, it will be the issue. Perhaps not common if you live in a warm climate, but here in Scotland most boats like yours have blown air heating installed. These must be wired direct to the battery and usually always take a little...

    Merc Alpha4 no longer available. What to replace it with?

    J no worries. The Rev 4 is a great prop to be fair. Often need to go down in pitch, as you’ve said though. That seems to be a common thing. It’s worth seeing if they come in one inch increments chris. I know some of the new expensive merc props certainly do. So an 18 might be good too ? If...

    Merc Alpha4 no longer available. What to replace it with?

    There is just no pleasing some folk. Maybe there is no point in you even asking such a question in the first place chris. Sounds like you know it all anyway. Was this question only posted...so you could answer it yourself ? What a man 😂 At least others now know fine well...not to even attempt to...

    Merc Alpha4 no longer available. What to replace it with?

    Jesus Chris. I’m not insisting on anything fella. Was just trying to help and share what I’ve picked up on props, from messing with them a fair bit. I’m amazed to be honest, that there is such a difference in a props ability to pick up weeds between a 3 blade and a 4 blade...but it’s something...

    Merc Alpha4 no longer available. What to replace it with?

    Urge you to try a tempest then chris. It’s just a 3 blade version of the Rev 4. Worth a shot, if you can get a hold of one to try.

    2000 Yamaha GP1200R- Fuel/Air Issue?

    Hi. Just make sure the filter is going the right way. Easy to get back to front. I take it the compression is ok on the engine ? If so, might just need to go through the whole carbs and fuel System. Or try running it straight off a know. Good fuel source

    volvo penta 4.3 GXI-J

    Most likely the diz cap or battery on this engine. That’s if your fuel is known to be good.

    tilt trim system

    Hi. That’s two different engines you’ve mentioned I think. The trim system is usually more suited to the outdrive that you have, I’d think.

    Overheating after impeller change

    Hi. Was there anything missing from the old impeller? Good chance you’ve maybe got part of it or the gasket stuck in the suction or discharge ports. Other than that, try bleeding the other water pump casing at the fitting there.

    Merc Alpha4 no longer available. What to replace it with?

    Agree. Fair comment. Happy to share what I’ve tried on a few similar boats and my own inboard. Tried so many props on that I was verging on silly. Haha.

    2003 4.3 MPI Mercruiser Problem

    Are your flappers melted too and have at some time allowed water to come back in ? An unsolved mystery water ingress...doesn’t often just vanish. All the best.

    New Boat Purchase - Stuck Manifold drain plug

    Hi. Depending on the manifold that’s on it now...there is a chance it’s been replaced at somepoint with an aftermarket one. Some of them have a fitting you can remove at the very rear and the front of them. Like a 22mm sized head. Just in case it helps.

    Prop for 60HP Bigfoot

    Hi. No 4 blade will give better top end than the same pitch and cut, 3 blade prop. Physics can’t allow it usually. The odd exception is the rev4 or bravo on occasion. But none of them are going onto your 60hp. Hope that helps.

    VesselView Mobile vs Lowrance Elite ti2 vs Smartcraft sc1000

    Hi. I can comment on the sc1000 and vessel view mobile. One of my boats has one..the other has the other. But just before starting...are you 100% sure your 2006 has smartcraft capability ?

    What boat and engine do you have now ?

    Merc Alpha4 no longer available. What to replace it with?

    I wouldn’t pay too much attention to the prop selector. It makes a good effort for very general advice...but it can’t possibly know how your particular boat will perform. The tempest is made for a range of set ups. I ran a tempest on my inboard v8 for a day. I knew it was too little pitch, but...

    2000 Yamaha GP1200R- Fuel/Air Issue?

    The reserve is just a lower suction from the tank. I’d suggest you have a restriction in the main fuel line. As in a check valve getting blocked or similar. Check that fuel filter too.
