    Hi So...my buddy has a maxum 2300 cuddy with a 5.7 carb and a 21" vengeance prop. Currently he is unsure whether it's a 1.62 or 1.47 ratio....I suspect the former.

    Thinking of changing from laser 2 to ballistic..same pitch

    Hi After my electrical problems are fixed (see other post...nightmare), I am thinking of trying a ballistic stainless 3 blade. Currently the laser 2 is pretty good, but could maybe do with a little more of the boat out the water at the stern. Don't get me wrong...there is only a foot or so in...

    Mercruiser MPI fault 54 and 56

On Friday night I had a wee full throttle blast. The engine didn't seem to be performing as well as I know it can, with...

    Mercruiser 5.7 exhaust bellow blowing

    Hi A friend in the marina had his exhaust bellow blow off for the third time since the new season started. Eventually I had a look at it for him, expecting the usual situation where he hadn't fitted it properly and having roughed up the surfaces. This was not the case.... Having pulled the...

    Mercruiser 2000 4.3 carb oil pressure gauge ohms reading

    Hi A friend of mine has the engine above and the oil pressure gauge is not functioning. I haven't looked into it much at all, apart from testing the voltage at the gauge. It reads 4 volts and the backlight doesn't even come on. 100% certain it isn't a genuine low oil pressure. I will be trying...

    Mercruiser Mpi fault code 152 ?

    Guys Towards the end of a lovely day out (in a rare 26oC Scottish Loch Lomond trip) a fault code beep raised its ugly head. 2 short beeps every minute exactly. The vessel view mobile app has shown a few of he normal codes, but I'm pretty sure the most recent fault code isn't normally there. It...

    Best speed and ballast location

    Hi guys. Bit of a novice having not wakeboarded for many years...I now have a 18ft bowrider with tower and hope to try a bit when the weather gets a bit warmer.

    Guys Totally puzzled this evening. I threw the boat in the water this afternoon after a semi service (weather was too good not to). Oil and filter changed, gear oil changed. Boat ran without fault all day, but on the way home there was what can only be described as a cooked roast ham smell...

    Where is the serial number ?

    Had a half arsed look for my serial number in the usual old mercruiser places (air cleaner cover and plate on the front behind serpentine belt) and can't see it. I'm sure the old mercs had a plate on the front, but this is a newer MPI model. The air filter cover space for it to be written is...
