Hello. Can someone tell me if that looks correct by eyeballing it or could I get some input. Just bought it a while back and just want to make sure everything is Okay. Any help would be greatly appreciated. It's a 2019 Suzuki 300 25 hours

Main reason I ask was when I took it out it seemed to take a while to get up on plane and it felt like once it was up it started to fly. But what would make it bog down on acceleration if I push the throttle down to quick. ?? I figured it was crap gas or spark plugs maybe. The boat sat for a while since 2019 when old owner replaced the Engine for his son. Only 22 hours when I bought it. Push start. All new electronics. Just wondering. Still haven't checked the plugs. I put some octane booster and fresh 93 in it and I changed the drive oil. So maybe I'm okay and I'm putting her in the water today.
 
Fresh fuel is essential.

The outboard is a long way from the transom so you could raise the engine 2 or 3 holes.

This will reduce drag and improve efficiency.
 
My rule was to start with the cavitation plate an inch and a half above the bottom of the hull and then trial and error rise it hole by hole until there is any cavitation.

Slow to get on the plane is more likely propeller pitch. You have a trade off between acceleration and top end/relaxed cruising
 
I've noticed you can only go up 1 more hole with the height adjustment.

A Long shaft outboard may be more suitable assuming yours is currently XL (25").
 
Engine height looks ok to me. As others have said, sluggish acceleration with high top speed is because you have a coarse propeller. That's a compromise choice you have to make - it's like having a car with only one gear and you gotta choose whether you want a high or a low gear. Nothing wrong with either choice - it depends on what you want.

Agree regarding the prop pitch.

However, the hull shape is very different to a "normal" boat in that the actual vertical transom part is about a foot from the outboard leg.

From memory the engine should be raised 1" for every 12" setback.

This because the water rises as it comes from the transom so you can set the leg higher....

So 1.5" plus 1" gives 2.5" for the ventilation plate to be above the keel line.

Yup. I'm not sure whether you're agreeing or disagreeing with me on engine height. I agree everything you say and your 2.5inch suggestion, but from the (imperfect) photos it looks about 2.5" so it looks ok to me :)

I think, rather remarkably, that we are all agreeing

If it was my boat I'd be putting the vent plate 2.5" above the keel line, so I think we agree on that as well.

Of course, dialling an outboard in for best performance is a black art as demonstrated by a line of 10 props in my workshop.

Enertia props are about £700 each so I must have a clear out....
