    To be Fair…for about $200 you can get a gadget that will tell you exactly what is going on.

    Alarm Going Off for Mercruiser 350 Mag MPI

    Mine beeped every now and then when the IAC failed. Only knew what it was when I looked at the alarms registered on the vessel view smart craft. Changed it. No beeps anymore. Think it was like 2 beeps every few minutes from memory.

    help figuring out what prop to buy

    It’s likely a very different hull I’d think. I’ve got an apex stepped hull with a pad at the rear of the hull too.

    The iac failing does similar to this.

    help figuring out what prop to buy

    Hi. I’m finding this particularly interesting. Some of your specs will be quite close to mine. Does that hull have any performance character to it ? Can’t quite exactly think it has or not. anyway. I’ve likely got around 300-310hp at a guess. 1.47 ratio alpha. 18ft stepped hull and pad...

    20 foot 1997 Maxum 2050 bowrider propeller question

    Had a chuckle at this. Hope you don’t mind. Pushing the boundaries of known physics a little there. 210hp 20ft performance lacking hull, 54 mph. Close to a prop slip figure that mti would kill for…and all with a 4 blade cheapo prop. Legendary! Fair play !

    1997 mercury 115 hp

    Hi. Is this a 2+2 engine. Think it might be at that age. Sorry to ask, but you’ll be aware of their character and their trademark behaviour? Either way, the fuel condition described isn’t good.

    4 blade prop

    Think that’s generally good advice. But some exceptions for sure AD. I actually found that going from a Merc 4 blade ally 21” to a 3 blade tempest plus 19” dropped the rpm by at least 50-100 rpm (because the 4 blade was on the limiter at 4900/4950) to about 4850 and increased speed by around 5...

    Yamaha 115 4 stroke, starting problem

    Hi. Any chance your fuel line from tank to engine is on the wrong direction? The primer bulbs are mostly unidirectional and one way.

    Yamaha 140?

    Hi Scott. Would that be a factor in the 80’s and 90’s ? We had 140 versions of the v4 here from around 84/85 up to around late 90’s I’m sure. Had the 130hp too. Most common was the 115 version…but I’m also aware that likely half of these or more, were probably upgraded to be about 130/140hp by...

    Cvx16 trial run

    Thanks zool. Wasn’t very brave with the trim on that occasion. Think she’d be around 60 gps there. At just about 60 and just over, she gets quite hairy…especially in U.K. choppy waters and lots of other quick boats around and causing wake. She seemed to settle out on the pad in calmer waters...

    Volvo 5.7 gxi c No Start

    I got why injectors might be blamed here. All apart from the fact that it’s reported it had a hard stop or cut out when running. Injectors surely wouldn’t cause that.

    Mercury Mariner Swap

    To be totally honest, I don’t know for absolute certain…but I’d be almost nearly certain, the answer is no.

    4 blade prop

    Hi. Think a few details are off. The HP number and the rpm number are both surely wrong. Hopefully the members can help, once the figures are good.

    I changed my outdrive !!!

    Hi. Yeah you’ll need more than a 17” with that ratio. At least a 19, more likely a 21

    I changed my outdrive !!!

    Not sure about your idea of 220hp. As far as I know, only the 4.3 mpi and a recent reman from quicksilver would be 220hp.

    Cvx16 trial run

    Some photos and footage of the special and rare cvx16 Roger Clarke U.K. built. 1984. Lovely machine and so glad to get her running again. Still prop testing but managed a 66 mph gps. Certainly more to come from her on a calmer day. Some photos of some other very special boats. Some of them, I’m...
