Ive adjusted the setting on the back which alters the reading but seems to move it in the wrong direction. Im starting to think the tacho might be at fault
i can only get the rev counter to work smoothly off of the alternator but is reading inaccurately.
I took the speed limiter off some time ago with no issues. As soon as i connect the tacho up to the - side of the coil it either doesn't work or it jumps and doesn't follow the engine speed. Could...
Hi ive just changed all the gauges on my dash to kus Analogue gauges.
Im having issues with getting the rev counter to read properly even after adjustment. ive taken the signal for the tacho away from the coil as this made the gauge very slow to respond if at all.
Its now on the w post on the...
Hes currently running 24p props but has tried 22 and26 with not alot of difference. It’s supposedly a 2:1 ratio.
Im wondering if the engine is actually the lower hp engine as theres no tally plates on the engine. If this was the case do you think it would still make the revs but not the power
Cheers
Evening im working on a boat that has had a yanmar 4LHA STP fitted. The boat previously did just shy of 30knots with an older Mercruiser diesel engine.
The engine is fitted into an offshore 25 sports fishing boat with a bravo 3 duo prop sterndrive. Would anyone be able to advise the correct...
Evening having issues with a volvo penta kad32 not making the revs. Have fitted a boost gauge onto the inlet manifold. Boost pressure completely falls off when supercharger is un plugged manually
Would the verdict be that the turbo is knackerd. Looking at the gap between the housing and the...
Hi would anyone be able to advise me on what resistance the water temp and oil pressure gauges work on. Ie ameican or european resistance there paired up with what I believe to be the original volvo penta gauges with the red and green scale. When I put a meter on the senders the water temp read...
Afternoon working on a boat with a volvo pents dp280 drive noticed that the most aft prop is bent. Ive Dti the shaft and the run out is about 0.18mm. Would anyone be able to advise what the maximum run out is and is 0.18mm with in tolerance Many thanks
Ahh ok was an idea I had to try and preserve the life of them.
I do flush them out with fresh water on the mooring by shutting off the water intake and plugging a hose pipe into the suction side of the raw water pump via a fitting. hopefully this will preserve the life of them.
What would you...
Hi im thinking of converting my exhaust manifolds to fresh water cooling as I have a closed loop system on this engine already. Has anyone done this and if so is there much work involved if so where do the pipes run too and from from the manifold
Many thanks Sam
Hi im looking at modernising my dashboard on my boat and using guages that match. Does anyone know if its possible to swap out the volvo penta square trim guage to a more common round trim guage. If so is there much wiring that needs to be altered to make this work.
Many thanks

Its an edelbrock 1409 il check the choke make sure its moving freely.
I did think it might be possibly be the carb getting heat soaked as it only had a paper gasket with no spacer and the fuel pipe is clipped to one of the heat exchanger pipes ( this engine has been modded indirect cooling)...
My aq271c starts up perfectly from cold, a couple of pumps of the throttle and shes running.
If i go for a run out anchor up and go to re start 30 mins later it takes quite alot of crancking to get it fired up again. Once its fired and you turn it off and start it again it will fire right up...
