    Smoking Engine and Mercruiser ignition switch question

    Was your outdrive tilted all the way up by any chance ? Either way…I would t be running any engine like this for too long on the muffs. If you need to…keep the revs low. Anyway. Best of luck.

    2024 75 Mercury outboard

    There is an analogue to digital module if you want the full unlimited use of the smart craft gauges. But I suspect that if you have analogue gauges and nothing works..and you have the analogue harness loom…there is something else going on. If you want to use analogue pitot Speedo for example...

    Anyone give me some info on this Engine please!

    Spot on above. Used to be about in the 70’s here in the UK. Not common though. Even back then.

    2012 seadoo rxp 260 only goes 30mph

    There is definitely something else going on here. Even the learner key fob will allow the ski to go fairly fast and certainly more than 10mph for sure.

    What's the round thingy,..??

    Yeah. Constantly rotates and doesn’t allow water to sit, obstructing view. Found commonly on commercial spec boats over the decades gone by. Pilot boats mostly all have these.

    Setting Timing on a 2002 VP5.7GXI-A

    Hi. This is often over complicated All you need to do is take the plugs out. Turn the engine to tdc on number one. Then you get the distributor assembly in your hands. Make sure the rotor is aligned with the very small “8” marking on the plastic casting of the lower housing…that’s where you...

    4.3 MPI Crank No Start / No Spark

    Hi. I’d check the following in this order Kill switch (sorry. Had to ask) The new coil. Are they getting continuity to earth back to the battery where they are mounted. The new cap. Is it installed properly. Is it just a new cap or a new whole assembly ? Are you getting a spark from the king...

    Tachometer Install

    You have the wires mixed up, I’d think. The meter is finding a path to ground or earth for it. See one of the posts above about wire colours and you’ll be right.

    Not sure. There was a service bulletin about these things on a few occasions

    Mercruiser 5.0 Mpi issue

    Haha. There has been a fair bit of prop testing…but the overwhelming majority of the hours have been spent at either 1200 rpm or about 2500/2600 rpm cruising at around mid to late 20’s.

    Mercruiser 5.0 Mpi issue

    Hi all. Just closing the issue and post… Thanks so much to you all ! It was indeed the distributor at fault. The shaft had vertical play of silly proportions!! Was allowed to move that much, it was cross firing, hitting the cap with the rotor and all sorts. This all caused two of the plugs to...

    Mercruiser 350 mag mpi distributor timing

    Hi. Literally just done this with my boat. You need to make sure the bottom crank pulley is absolutely at the tdc markings. On the compression stroke too. Can be done with watching a compression gauge if required. Then. You need to look for the line or marking on the distributor shaft. Make...

    1985 Black Max 150 Hp Leaks oil out of reservoir cap. I replaced the cap and still leaking.

    Hi duke dog. I may stand to be corrected, but as far as I understand it, there are slight variances in the design between these particular motor’s pump design…compared to say a similar or slightly later era 3 cylinder 90hp for example. I’ve just known of far too many in the local to go wrong...

    Mercruiser 5.0 Mpi issue

    Haha. Great advice at the end there. Brilliant. Yeah. To be fair. That’s a really good point it wouldn’t be the first time it hasn’t seated too well in the past. I’ve been one of the biggest critics of this design on here for years now. You might just be right about that causing a little...

    Mercruiser 5.0 Mpi issue

    Thanks Stinnet. I’ve had her for about 10 years now. Went through about 5/6 diz caps over the years. She hasn’t been in use for a few years recently. Really need to get back to have a look at her. But fearing the worst for her. I’ll report back when I get a proper look. In the meantime, I’d...

    Mercruiser 5.0 Mpi issue

    Hi all ! Has anyone previously known or came across a situation where the shaft on the distributor appears to be bent or off centre ? It was dark and not thoroughly looked at properly at the time. The boat is not currently anywhere near me and haven’t been back to it since. But a Quick Look at...
