    Extended trim anode of no use !

    Bit of a bugger today. After previous posts about trying to counter act my horrendous torque steer at slow speed and low planing speeds...some will know I managed to buy the extended trim tab anode that normally sits out the way of the larger props. turns out...even they don’t sit far enough...

    Anyone ran a tempest plus on a heavy open bow ?

    Having repropped My 115 mercury outboard, I find myself with a spare tempest plus that will go on my other V8 mpi alpha drive of a pitch that should act well as an all rounder. Anyone tried the Tempest plus on a fairly heavy 1400kg 18ft open bow hull with a fair bit of power to turn it ? Curious...

    Mercury 115 2.1l 4 stroke 2016 oil drain

    As many will know...this has a clever oil drain fitting on it that you can just attach a piece of hose to then crack open the fitting. It’s down near the mid section. I see online that most are just cracking that open and draining the sump without running the engine first. I’ve always ran...

    Wee Run in the Rib and Sib

    Managed out a wee run in my Brigg 2.7 Rib. My older Yamaha 8 2 stroke had a blocked tell tale so quickly got my newer and last of the 2 stroke made 8hp on it instead. The wee Brigg goes so well. A few speeds over 20 mph recorded GPS. Great fun. Have a look below. searider, you’ll like this wee...

    Mercury 115 CT 2.1l trim relief valve

    Hi all i might have asked this before, but this fairly new to me engine is an amazing thing, being one of the new mercs...but only thing bothering me with it is that it doesn’t quite trim up as high as I’d like a full throttle. It will go to a fair level of trim, then open the relief valve (I...

    Mercruiser MPi fuelling self adjustment

    Hi all...one for the guys that know more than I on the matter... Although I had strongly suspected that the mpi small blocks were able to adjust timing and fuelling to adapt to different octane ratings in fuel, only today I read that they actually do. I had wondered this because occasionally I...

    Old Yamaha FXHO MR1 as quick as they get

    Wee link to the GPS tracker the last time the old FXHO had a run. For those that are familiar with this model, she is pushing the boundaries for a naturally aspirated ski then some. Amazing 67 mph gps from this thing is incredible. She is usually a steady 63-65 but the last run shows a peak 67...

    Mercruiser GM V6 and V8 oil pressure

    Hi all On my own MPi V8 and any other GM V6 and V8 I’ve ever had or been on, the oil pressure at idle and good oil has always been around 40 psi at idle and at worst about 35psi at idle with used oil. I was literally just watching a water test from a local dealer there. He was showing the...

    Childish and silly, I realise, but does anyone have exact and precise guidelines about drilling the exhaust chamber to exit above the waterline? thanks in advance.

    Any improvement noticed by porting etc ?

    Hi Im aware that GM engines we all know and love so well, although reliable and robust things...they are perhaps not exactly cutting edge or the finest example of precision engineering. I was recently told from a fella, about how he saw a noticeable difference in his 4.3 motor, after porting...

    Mercury command thrust trim anode fin

    Likely not a common thing but thought I’d see if anyone had been there before. had anyone had any decent results to reduce torque steer on the larger gear case outboards (without power steering or anti feedback steering) by fitting a trim anode fin ? I’ve just managed to order the special...

    Origo dometic 1500 (Where to find)

    Long shot really, but wondering if any of my North American ship mates might know of a means to get an Origo or dometic 1500 model single burner alcohol stove to me ? One of my boats came fitted with one of these from new. Mine was missing when I bought her. They don’t make them anymore and like...

    TRS or Bravo even Bravo XR ?

    I’ll keep this brief. Long story short. I’m trying to help a boating friend best I can with a ridiculous machine he has almost completed. But such a machine is not what I’m used to at all. Far from it. He has one of only 18 built tunnel hull boats. They were made in the late 70’s and one came...

    Hi all just this evening I was involved in trying to identify a drive, from pics. No idea of serial number yet. likely the more experienced than I will answer this very quickly. The drive was claimed to be a pre alpha (as some say), but it has a squared cav plate like a gen 1 alpha and what...

    Enertia and me boring you again

    Ok. So as most have gathered by now...I have an unhealthy (for my bank balance at least) obsession with props. I wasn’t going to bore you again, but can’t help it. I bought yet another enertia of 20” for my big gearcase mariner merc 115 CT (new model 2.1) on the 19ft cuddy. delighted to say...

    I always watch this guys videos with interest. Really great channel with totally neutral testing. I was aware you guys over the pond have complaints about the ethanol blended fuel and it’s issues...but my goodness, I had no idea how horrible this stuff was. Simply horrendous stuff. I’m so glad...
