    smartcraft confusion

    Ok. I think what might be happening is…any unused ports on that junction box…need to have the yellow terminator blank fitted. If you aren’t using all 4 ports…any unused need to have this yellow one. I think your picture had one yellow and one purple blank ? So do you have a cable from engine to...

    smartcraft confusion

    Not totally sure, but I think you can either use the pitot sensor from engine or a smart craft paddle wheel. I have both, but only use the paddle wheel sensor. I don’t know what that harness is called, but I know the gauges all feed into it then at the other end…there is a plug going to the...

    smartcraft confusion

    Hi. All the gauges there should then feed into a harness that plugs into one of them. Then goes down to the network 4 way box into one of the ports. That 4 way box should have a feed from a plug on the engine. I also have the newer gauges, but also the vessel view mobile. The mobile device plugs...

    Just the one or two then, haha. Excellent as always AD.

    Mercruiser 5.0 MPI fuel problems

    Ok. Got you. So I think you have a few issues going on. Someone better versed than I will be able to tell you exactly what can make the 2 beeps. But the well known ones are voltage (may be relevant), low gear oil, IAC (think this might be one of your issues perhaps). Other than that..the well...

    Mercruiser 5.0 MPI fuel problems

    Initially, I’m thinking your issue is an electrical issue. Perhaps somewhere around having a reliable and constant continuity to the ecu or more in particular, the kill switch wiring perhaps. But only thing you’ve said that would throw that theory out…was the mention of it not cranking...

    What engine ?

    3 or 4 blade prop for H190 SS.

    Hi. Also…if it helps. You won’t be able to go far past the 4800. There is a limiter that will kick in and alarm at around 4950ish. What boat is it you have ? Sorry if I missed that detail. I’ve propped a couple of 18/19ft bowriders with this engine. If I can help any.

    Want to make my 350’s louder

    Look at the Corsa Marine site. Go to guys for that. They actually did a feature on my own wee boat. Very flattering!

    3 or 4 blade prop for H190 SS.

    4.3 mpi is 4400-4800 rpm range, I’m sure.

    Anyone Seen these?

    Jumping the gun a little I think. We still don’t know if it is an upgrade at all !

    Gear ratio change/unknown oem prop

    I’d think you’d be right on that. To be honest, mine is the only one I’ve known with the highest gear ratio available. But I’m aware it was certainly an option over the years. It’s a 1.47 I have. Dare say the older option would be the 1.5…if it was back then.

    One manifold hot (5.0)

    Was thinking more if one of them was blocking the flow perhaps ?

    One manifold hot (5.0)

    I’d say it’s almost certainly related. You may need to make sure the other one is where it should be too.

    “Oil level” plug vs “vent” plug on lower unit of 2003 90hp Mercury

    Hi. Not that I’m questioning your familiarity at all…but perhaps maybe your eyesight is as mine is these days…are you sure the small seal gasket isn’t stuck in there at the base of the threads ? Usually they stick in there. Can be blue or yellow usually. Normally involves a wee pick with a fine...

    Gear ratio change/unknown oem prop

    Do you know it was definitely a 1.5 ratio ? Most 5.0 weren’t, I’d think. Although some definitely are. I have a 1.47 ratio on my 5.0. But it has much more power than that 5.0.

  19. Q

    Anyone Seen these?

    I’ve found my tempest plus is a better all round prop on one of my boats for sure. Not quite as quick…but only a mph or 2 in it. But certainly better at acceleration and much more efficient at slow speeds and cruising than the enertia. But if I didn’t have the tempest, I wouldn’t know any...

    Anyone Seen these?

    Until there is a proper test done…we have no idea if it is any better on fuel, than a good equivalent 3 blade. No idea at all. We just can’t trust these reviews. The prop slip numbers show 0 and negative slip…Total BS.
