    Wonder if I should go IO again or go OB?

    AD. I totally get what you are saying here. Despite me now (unbelievably) being a huge fan of the current 115 Mercury CT 4 stroke I have on one of my boats. The one I use 99% of the time…I honestly can’t sing it’s praises enough…but the huge and overwhelming fact of the matter, with my...

    Mercruiser 5.0 Won’t Reach Operating Temp

    Check the actual temp for sure. My v8 mpi dash gauge shows about 10-15o difference from the actual reading from smartcraft ecu. Sits steady at 152 usually

    Can we talk about 4 stroke mercury’s from the early 2000’s?

    My personal view is that although at the time, is was a good effort and probably required, that the industry had to go down this road…but I also think that these early efforts just couldn’t compare to the time tested and trusted engines that came before…the 2 strokes. The early 4 strokes were...

    Ranger boat lever function question

    One is your lanyard. Other could be a couple of things. So you have trim tabs ?

    94 four winns horizon prop issues. Sounds like its coming apart

    Sounds likely to be related to the issue. Prop hub would be the best of the possible outcomes. Good luck.

    You’ll need the Mercury gateway for that. Best of luck.

    Top speed?

    You should be able to achieve 40 mph gps or a little more, with a good prop.

    Mercury 2020 115 Trim Sensor to Smartach

    Hi. Slightly different, I’m aware. But I have this engine too, but with the smartcraft sc gauges. To show the trim indicating, you need to initially calibrate it. Go into the calibration mode and set it up. Will ask you to move the trim to certain positions then save each of them. Should work...

    1989 Volvo Penta AQ271c cooling system

    Yeah. They can suffer and end up causing a loss of prime to the pump.

    Propeller swap Volvo dp 290 and newer dps outdrive.

    Hi. As far as I know…VP don’t offer the b series prop that most of these originally came with. The J series has replaced them, I’m sure. At an outrageous cost too. Not normally one to suggest straying from the OEM for parts, but I happen to know that the aftermarket alternative offered by...

    7.4mpi just started running rough and with gas coming out exhaust

    Hi. Couple of thoughts here. From the simple perspective. A couple of simple things that can make these run bad would be; Your alternator failing or a bad connection somewhere causing a low voltage or no charge voltage. This means your ignition system won’t have enough to run the thing properly...

    Need help with year and horsepower of this motor , Can someone please help me ?

    Hi. That’s two different engine type cowlings altogether. The engine itself looks very much to me like an early 80’s 2.0 v6 150 or 135. I’ve one the same. The other picture of the thunder bolt casing is off a straight 6 engine.

    94 four winns horizon prop issues. Sounds like its coming apart

    Is it possible you’ve hit the bottom and it’s the prop hub that’s sacrificed

    Propeller pitch

    If your bravo is a bravo 1 and the usual 1.5 ratio…I’d be starting with a 15-17”. But it’s anyone guess really until you try it out. Also depending on what 5.0 you have too.

    Volvo Penta SX Prop ID

    The boat I use it on is just all about top end really to be fair. I wish she was light, haha. She’s likely the heaviest 18ft boat I’m aware of. She’s 1500kgs dry. She does have a pad and a step to help things along though.

    Volvo Penta SX Prop ID

    Good comment Scott. I just admit. I might be warming to the abilities of a 4 blade, on a light big outboard powered fast boat. They seem to stabilise them at speed for sure.

    Rough to start, barely idles, runs great above 2000 RPM's

    It will be the tks enrichment issue. Very common.

    Volvo Penta SX Prop ID

    Those Rev 4s do so well, for a 4 blade eh. The bravo 4 blade is also very good. Really surprised at the figures there from the enertia though. Can be a funny prop to get dialled in. I found them at their best if you gradually trim them up slowly to keep it hooked up. They take so much trim

    Volvo Penta SX Prop ID

    No worries. I thought the part number may have started with an “8” if it was VP. Probably wrong though. Doesn’t look too great a quality, with its rust showing perhaps.

    2005 350 mag mpi mie overheating

    Fair chance that you might have fried the exhaust flappers and they are blocking the cooling flow on its way out…that’s if she overheated previously.
