    Prop Pitch questions

    Can often lose top end with more pitch, depending on what you see now, with less pitch. Some hulls like more rpm from the prop to give a little lift.

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

    I’ve got a comparison that’s relevant. Posted it before I’m sure. regal 1900 stepped bowrider 4.3 mpi alpha 21” spitfire 4 blade ran to the limiter at about 4950 at 48 mph from memory. The owner was about to order a 21” stainless 3 blade thinking he would be about right. In the meantime he...

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

    Scott. What pitch was that rev 4 that managed quicker than the enertia. Would love to see a tempest plus of same pitch on your boat and see how it goes. I’ve been amazed with the Tempest so far.

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

    Hi chris. I think this is a tough one. Having only the vengeance to compare, I think isn’t doing the 3 blade props any justice. They are terrible props, to be honest. I’d urge you to try a tempest plus of the same pitch. You’ll find so much more grunt everywhere in the range and I’ll bet my life...

    Mercruiser 350 mag MIE ECM

    It’s not a normal coil and Diz. Not really a coil and diz at all, to be honest.

    Mercruiser 6.2 whining noise

    Mine has always done it. Had the boat since it was only about 50 hours on it. 700 on her now and 6 years later. Pretty certain it’s normal. remember and keep an eye on the diz cap with these. Most common issue there is on them.

    Mercruiser 6.2 whining noise

    I’ve the same noise. I think it’s the fuel pump or perhaps the oil filter bypass...if it has one. I’m more a diesel man and perhaps thinking wrongly. https://photos.app.goo.gl/PZVZVtFxtJCwa7GE7

    Mercruiser 6.2 whining noise

    Is this just happening when the engine is cold ? Perhaps a filter bypass noise. Other thing might be the power steering pump. Does it change noise when moving the steering ? Or as said...fuel pump. I don’t think it’s a noise to worry about. I’ve a video of my mpi running. I’ll go look and see. I...

    Yeah. You’d think it would be one or the other, causing the issue Jim ? Not much else to stop it.

    Bought a new boat..loooads of questions LOL

    A friend had one of these for a few years. Was on it lots. Not usually a fan of maxums and similar....but I was really impressed with how stable she was, as well as how well she went too. Fairly capable in choppy water too. Blistering quick for a boat that size. Has a stepped hull. His was...

So just a bit of a difference from your assumption 😂. but seriously, there wasn’t much difference at all. But the main thing was that the 3.0 was reliable. No 3.7 has ever...

    2000 Yamaha GP1200R- Fuel/Air Issue?

    Hi. I think this is the non power valve 1200 more reliable version, going by the year. Not much to go wrong with these motors to be fair. Id say your right in thinking it’s fuel related. I’ve never had the triple like yours, but had the twin 800r ski and got to know that very well with a...

    Water pump on 1986 yamaha 115

    Probably 6E5-44352-00 but double check. The v4 and V6 around that era had the same impeller.

    PLEASE HELP

    Hi. The 3.0 4 cylinder will drop in on the same mounts pattern. Depending on the boat, you’ll get away with a prop change to suit her right. All 3 of the boats I know of that have had the 3.0 put in instead of the 3.7 didn’t need an outdrive gear ratio change. Just the prop. Wasn’t a huge...

    Ok. So I’d say your gauge is very optimistic but still giving an idea that the engine itself is ok. I’d defo look at that gear oil now.

    What are the essential tools to keep on board?

    Anchor and a mobile phone always handy. Cable ties are great. Adjustable spanner and screwdrivers. Extra beers can help too, if all else fails
