    oil pump too perhaps ? Not an expert though

    Tell Tail pressure difference

    I might think about taking the tell tale hose off at its source on the engine..check for any salt deposit build up. Had the very same thing on a smaller yam recently. Engine wasn't overheating, just a weaker tell tale than it should be...Was just a little tiny bit sitting there. pees like a race...

    High Voltage Yamaha two stroke 75 HP 2015 model

    is it tested as 17v at the actual battery and with a meter ? or is this read from a gauge on the dash ?

    2004 5.7 Thunderbolt turns over but won't start

    I would try it using a known fresh fuel source, like feeding it fuel from a small tank of fresh fuel.and after draining carb, if possible. Surely the money would be on the issue being fuel related. carb may have to come off, if she has had any crappy fuel even close to it. Otherwise its time for...

    Maybe my turn for new boat time

    Yeah. She’s a Fletcher. Well known U.K. make…always good fast narrow deep v hulls on them. Fletcher were known for their racing heritage back in the day.

    Mercruiser 4.3 Dying Problem

    sounds like bad fuel...try running her off a remote tank of fuel from a can. But I would suggest that once crap fuel has made its way to the engine (especially a carb)...most times the carb needs to come off.

    4.3 cruiser rough running

    I am sure you'll know already...but make sure its 100% fresh fuel you're giving her. Bad fuel will result in exactly the described too.

    Maybe my turn for new boat time

    I hear you AD...having always turned my nose up at any 4 stroke outboard boat previously, then just the other year getting a cuddy that had a 2016 new generation merc 4 stroke on it...just for sensible general use, I wasn't expecting much, but the price I paid was a few grand less than the...

    Long cranking and turnover to start after warm. Questions about vapor lock and leaky Injectors

    What you have said is very typical of battery issues on a gxi or mpi engine. Despite cranking fairly healthy, if the battery is not utterly perfect, it will not have enough to fire up the engine when loaded up by cranking over. honestly, it is well worth trying another battery. such a common...

    4.3 MPI Possible ECM issues

    Good call Chris. Spot on. Presumed they be the same. But you’re right.

    1990 Bayliner Capri 2050 5.0 V8 200hp

    Every day a school day on here chris. I’ve honestly never known one of these here in the U.K. weird they made one with less power than some 4.3’s of the same age. I had a VP 4.3 (aq205) from 89 with 205hp. Think merc made one then with 190ish too. Or maybe more.

    1990 Bayliner Capri 2050 5.0 V8 200hp

    Man. That’s a first for me. Never known they did this. I see the rpm rating has been de rated from the usual 5.0 that age too. Fair play. Weird that they made this alongside a 4.3 with the same power just about.

    4.3 MPI Possible ECM issues

    also wondering about the mention of the fuel pump staying on. does it cut off a few secs after the beep when turning ignition on (but not starting) ? There are two fuel pumps on these, as you'll know too.

    Seadoo jet boat stalling

    I think you need to go re check your engine details. I would have money on, that its not a 4.3 litre v6 2 stroke. I think once you know, it may be easier to get your issue sorted out...sure sounds like a fuel issue though. keep a close eye on that oil injection system, if its the engine I...

    4.3 MPI Possible ECM issues

    Hi, my thought around this are that around asking if you might have a mix of components here after an engine transplant. I ask this only because I have it in my head that there might not have been such a thing as an mpi 4.3 in 2001 ? I may be wrong...I am aware there were some early v8 mpi from...

    Shift Interrupter Switch Unhooked however...

    I would think, if it actually was 900 rpm, you would never get her out of gear...it surely won't be that high in reality. you would be smashing into gear at that. the drive wouldn't last long at all.

    1990 Bayliner Capri 2050 5.0 V8 200hp

    Id say you are not finding anything in a search, because its not 200hp. It has a little more than that. Around 220hp would be the number for an early 90's carb 5.0. some were 230 even, from memory.
