    cant find out the year of 90hp yamaha

    If not for folks in one territory…the other wouldn’t exist Perhaps. There are more Scottish and Irish heritage in the US than there is in Scotland and Ireland. The man often credited with the beginnings of the US navy is from a place around 20/30 miles from me now. Lots of shared origins to be...

    Wonder if I should go IO again or go OB?

    Must admit. I unexpectedly love my new merc 115 2.1 litre outboard. It’s just the pinnacle of mid range outboards right now and light years ahead of any other brand in the game. No doubt about it. But it doesn’t excite me the way my old GM V8 Mpi does, when I hear her start up through the side...

    another useful post. Thanks ! I’ll need to give in on this one. Initially tried to help the fella out..only to get useless, silly and offensive posts from the flanks…for what reason, I’m not sure. I won’t probe any further…often when things like this happen…the guy doing it can be suffering...

    2015 115 Merc on 20' pontoon

    You’ll be right I’m sure Ahicks. No doubt. Suppose all I can offer is around this particular engine. I have no experience with other 4 strikes this size at all. Only W we had this and a small merc 3.5

    Thanks FS…I’ll know better next time I think. Sounds like there are no Yamaha’s in the US that came from Japan 😂

    2015 115 Merc on 20' pontoon

    This particular 4 stroke definitely runs at its best up near 6000 rpm. No doubt about it. Just from experience and having a bit of a prop perfection ocd thing. Fuel economy at cruising speed is much better too, when set up near the top. Just what I’ve found with mine. After 1000 hours clocked on...

    Mercruiser 5.7 closed cooling shaft drive raw water impeller

    Superb Chris. Once again, can’t thank you enough. The boat isn’t that local to me, so was thinking initially to go armed with the part in hand…but having read this…I think I’ll take your advice and take the thing off first and see exactly what it is. Thanks again…Allan.

    Mercruiser 5.7 closed cooling shaft drive raw water impeller

    Excellent Chris. After reading your advice…think I might have found the part. I hope. Does 59362t1 sound about right ?

    Mercruiser 5.7 closed cooling shaft drive raw water impeller

    Thanks Chris. Appreciated. I perhaps should have worded it better. When I said reversed…I meant that the actual engine is 180 degrees from the normal outdrive engine. As in its drive end is forward facing and into a v drive, then shaft drive. Brilliant info Chris.

    Mercruiser 5.7 closed cooling shaft drive raw water impeller

    Hi all, Not a set up I’m familiar with at all and haven’t had a look in person, but I’ve committed to replacing a friends raw water impeller on his set up as above. Does anyone have an idea of the part number for this ? She’s from around ‘97-99 with closed cooling and shaft driven (engine is...

    2015 115 Merc on 20' pontoon

    Definitely think the CT makes a huge difference. I’d also say that having tried lots of props on my CT…she definitely is at her best when propped right at the very top of the rpm range. I run a tempest plus to just about or a little over 6000 rpm. Propped like this, the cruising speed is much...

    Depends where he is. As mentioned in my first post. Europe is a big place. Is that data tag picture I sent above of any sense to you guys over there ? Not sure how similar they are.

    So this is a local engine I’ve photographed for an example. She’s a 1989 Yamaha 225 v6 2 stroke.

    My goodness. Have I wronged you in another life. That’s the European chart. I’m certainly not ashamed of where I live. I live on the Bonnie banks of Loch Lomond. Not far from where some of your founding fathers would have had roots. Have I given enough info for you ? Anything else you need ...

    Chris Craft - Which should i purchase

    They would likely have the newer trim system with the separate resovoir id think. Agree on the Ford engines, though they weren’t used too often perhaps

    Hi Lou. Don’t think there is usually an issue getting parts for VP that age.

    Vibration at low speed

    It could be other things too. More thinking around engine causing it. Bad fuel, water getting in from frost damage or the famous diz cap failing.

    Vibration at low speed

    Any pics of the prop ? Presumably the thrust washer is in place ? What prop you have on her ? What rpm is she at when this happens
