    Question of HP

    Anyone’s guess these days. The new merc 4 strokes have totally changed my way of thinking the old way. I know that a new mercury 115 2.1 4 stroke is way more powerful than a mercury 125 optimax for sure. Likely it’s around 130-140hp in reality. Perhaps an exception to most maybe. Not sure.

    Looking for Opinions on Super Bowriders

    Definitely a warm climate machine. I’ve had the bow cover off my boat about 4 times in 5 years. Haha.

    Volvo Penta prop help

    Ah. I was perhaps referring more to the gxi 5.7 original post. But great to hear all related details. I take it you have a big block, with those lower rpm ? Just read it’s an 8.1 you have. I’d think your rpm limiter would come in around just short of 4800 anyway. Wouldn’t worry about the...

    Volvo Penta prop help

    Hi. If these are the original props for the boat...I’d be totally amazed if the props are the issue. This would be the first time I’ve heard of a Volvo Penta DP set up to be propped anything other than perfectly almost. you sure it’s nothing else going on ? You want to be between 4600-5000 rpm...

    Engine won’t turn over

    Think you might be at risk of further damaging the outdrive. It’s almost certainly the issue.

    Prop selection help

    No. Tempest 19 had more rpm than a 20” enertia. By about 100/120 rpm. But lower rpm than a 21” aluminium 4 blade spitfire.

    Zerk size on 2006 Optimax 200

    Read it again. If you still don’t understand the grammar and the resultant deflection to another matter...forget it

    Zerk size on 2006 Optimax 200

    Robby. Maybe just forget it. But if you needing reassurance, then it was a reply to someone else’s post about a grease gun being adjustable. don’t worry about it. Don’t let it ruin your day. All the best.

    Merc 9.9 High Revs Going Into Reverse

    Does this have remote throttle and gears ? If it does then sounds like it’s related to that.

    Prop selection help

    It’s usually an unknown going 4 to 3 blade. The tempest is another prop that can behave a little off too. I know recently when propping a boat for a friend a 19” tempest actually dropped the rpm from the previous fitted 21” 4 blade spitfire ally. I also know that on my outboard boat, there is a...

    Prop selection help

    Tempest plus or enertia. Tempest easier to get a hold of used. Both incredible props.

    Zerk size on 2006 Optimax 200

    Robby. Have a read again please. You’ve miss understood what I’ve said. Laughing at inexperience is something I’ve never been guilty of. Ignorance is just ignorance. These are your assumptions. Not the reality of the comment. As suggested. Have another read. Don’t be so paranoid and you’ll do...

    350 mag mpi 2011, low fuel pressure

    I’d check that fuel pump system and regulator. but only thing confusing me is if it has a smell of fuel and running rich like you say...that’s the opposite of a sign of not enough fuel or a restriction. Perhaps I’m now thinking along the lines of an injector staying open when it should be ...

    OMC Chevy 5.7 just cuts out.

    Sounds electrical for sure. I’d check all the usual battery terminals and the main earths. Also the lanyard kill switch system too.

    Single point drain tech tip

    Excellent. I always drain using the valve. Then take off each quick connect fitting. Pour in some AF and price it comes out each individual drain at the source. Then you’ve proven they aren’t blocked. Connect it all back up again. Fill to the brim with AF. Block and exhausts until it comes out...

    Engine won’t turn over

    Got to be the outdrive then. If there is nothing staring at you in cylinders that’s obviously dry or sticking.
  17. Q

    Size and pitch for prop

    Even telling us what outdrive it is might help. If it’s a merc alpha or pre alpha...and you still just need to start somewhere...I’d start with a 17” pitch black max and go from there. Likely only a couple of inches off at worse.

    Engine won’t turn over

    Pull the plugs first. See what happens.
  19. Q

    Intermittent oil pressure readings

    Oil pressure sender sounds like the issue here. I’d also cation that if that 180 degrees reading is genuine and off the smart craft too...you are on the verge of overheating...or even on it.
  20. Q

    Smartcraft error message "A shift fault has occured."

    Was going to say. Be the shift interupt switch or more likely on occasion...the switch needs slightly adjusted my only mm’s if the throttle assembly is contacting it. Happened to mine. Doesn’t clear the error until you get it cleared.
