Thank you - that’s very helpful, and good to know. The shop said they actually got up to 5800 and 48mph(!) just after their video clip ended so that’s more than adequate for me messing about on the U.K. East Coast. and I don’t intend to run flat out all day.

To close this off (I always try and update as to the outcome) - the shop just sent me a video clip of the boat now running at 5700rpm and 47mph. As she has bottom paint (clean) I think that’s about as good as factory. The fuel system was manky - new HP fuel pump (as output was 20psi instead of...

Thanks for this. Yep - the shop thought lack of performance was due to the prop; as I feared, the prop was a red herring and it looks like fuel/injector cleanliness was the issue. They called this morning, having replaced the injectors it’s now apparently running at 5700 and 45mph, which is...

Thanks for the replies. Went to collect the boat today and it’s not been fixed correctly - 4000rpm WOT. So I think it’s unlikely to be the prop. All filters and the VST have been changed or cleaned, as well as a new high pressure fuel pump, so am hoping it’s the injectors. Annoying that they...

Good evening from the U.K. I have a Grady White 180 Sportsman. Can you let me know what size props you are running and what revs you get at WOT? I have a Yamaha F150 from 2008, WOT is 5200rpm and gives 40mph. Hull is completely clean, but has been painted/antifouled. My Propeller is 13.75xM19...

Ok - thank you. That’s interesting - my own motor is definitely 2007, but it also says “08” on the plate.

Thank you for the good advice. I actually just bought the boat - over here in the U.K. Grady White’s are quite rare. I’m super happy with it. The engine has all documentation and receipts and service records with it, and has done just 224hours. I’m pretty sure the cowling hasn’t been changed...

Hi. Can anyone please advise in which year the logos on the cowling of a Yamaha F150 changed, to include the “propeller” icon? I recently viewed a GW180 with this engine, stated to be 2007, and it says “Yamaha” “Four Stroke” and includes the propeller icon as well, whereas research on the web...
