    Popping and shaking

    It could also be that you are getting a weak ignition. That will cause similar on the plugs and running like it is. Have you checked your stator/regulator output and coils ? Easier is to put a meter on the battery if she has one

    4 Blade?

    I’ve heard folk mention around better slow speed manoeuvring apparently. Must admit I’ve not ever noticed a difference between them. As for the fuel mileage. That’s certainly not going to be the case I’m afraid. The more blades a prop has….the less efficient it is. Absolutely I’m afraid. They...

    4 Blade?

    Why do you want a 4 blade ? You’d need to have a good reason really.

    Merc 4 stroke worn out with low hours

    Check your oil isn’t full of fuel

    Mercruiser 4.3 injection without any ignition

    Yeah. Definitely aware of that. But just pointing out that it may be the wrong set up altogether. And definitely for certain…there should be not plug inserted into the port on the distributor base on that engine. Maybe it’s not plugged into it…but worth a mention

    Mercruiser 4.3 injection without any ignition

    Hi. See the crank position sensor you mention…does that have a yellow weather cap on it there ? Hard to make out. Yellow caps on these mpi plugs normally mean a terminator resistor. A purple weather cap is what it might just should have had. Where is that plugged into ? Presumably not the...

    2006 225 4stroke runs poor until warmed up.

    Hi. Apart from the above (which might have given you an alarm perhaps), you may be losing the prime of your fuel system in the vicinity of the supply to or the VST. Meaning you are having to get air through the pumps and injectors for a while until it’s purged. Or you may have issues like the...

    2006 Mercury Bigfoot 60HP fuel issues

    Oh. Forgot to say earlier. Did you bleed the fuel rail too ?

    Popping and shaking

    Personally always found chasing assumed issues with an outboard on muffs and not in its natural state of operation, can be end up in hours you’ll wish you had back later in life !

    2006 Mercury Bigfoot 60HP fuel issues

    Hi. Did you clean or replace the strainer on the fuel rail ? Presumably it’s the pumps in the vst you replaced ? Was it assembled properly afterwards ? Sometimes o rings can be the cause of this. But certainly have a look at that filter strainer in the fuel rail. Presumably there is a strainer...

    New prop

    I think a prop with cup added, will usually drop a few rpm on hulls that can’t take advantage of it fully. You didn’t say what engine you have, but I’d assume at low 5000’s you are only just in the rpm range and the mention of running with only 2 on board, you’ll be lugging that engine with any...

    Prop for 1995 mercury 200 efi

    Yeah. Something definitely isn’t right here. Your prop slip is just enormous. If your tacho is correct and the gps speed is correct…something isn’t quite right at all.

    Prop for 1995 mercury 200 efi

    I think you have other issue maybe. You wouldn’t want more pitch after those numbers surely. I’d do a compression check

    Penta 4.3 GL in saltwater?

    Hi. There are plenty of raw water cooled GM engines just like this, still surviving after 30 and 40 years in the salt. All about taking care of them when they come out the water. Any corrosion suffered internally, is without doubt as a result of sitting over winter empty of any fluid medium or...

    Yamaha runs awesome, will not re-start after running???

    Is that the battery voltage when it’s running ?

    Mercury

    Were you not tempted to get the larger HP version of that engine ? The 75-115 are all the same engine and weight. So although it’s weight is exceptionally little for a 115…it’s perhaps on the heavy side for a 75 version. Exceptionally powerful things, I’ve found The CT version is brilliant

    Hydraulic steering

    The baystar system would be perfect for that set up. It’s the smaller sea star product. I have it. What a difference it makes. Amazing

    Boggs down

    Honestly. What you’ve described is typical float issues. Worth another look. If not..it’s a fuel starvation issue at least

    Prop for 1995 mercury 200 efi

    Hi. That will only come in the size your after anyway. For larger gear case like yours. Just be the usual flo torque hub kit that you’d use in most any other merc prop for your engine. I’d recommend the uprated hub kit that prevents prop rattle at slow speeds.
  20. Q

    90EFI mercury model 1F904531D S/N 2B185185. Changed the low pressure fuel pump in the FSM. Will not fire off, it’s getting fuel.

    With the cover off, turn the ignition on and listen closely for the pump coming on for a second or two. You’ll soon know if there is air in it. Then press the shrader valve on the fuel rail whilst someone does it at the key again. You’ll likely have air in there. It’s going to take a while to...
