Hi Adam

Do you still have the P19 for sale? If so could you let me know the P&P to Central Scotland.

Cheers
Dave

Hi Dave - which one of the props? I still have the 19 Laser and also the re-worked 19 Ballistic

It is looking like £12 postage - can get cheaper but don't like using Hermes as had bad problems with them in the past.

Thanks
Adam

I have never really used Solas Props as don't really rate them as great performance props - especially with stepped hulls. Sounds a bit large on diameter too.

But as with all set-ups - props are only part of the solution and there will be many aspects to combine in addition: prop height, weight distribution, set-back etc. Then whether to run a lifter or not?, or just a step off bracket?
gearbox nose cone?

But generally should be trying to set up boat to run near to neutral trim for best results, raising engine rpm nearer to max etc.

Thanks, I think 5,600 rpm is about my max rpm, as the engine gets to that rpm with about Ĺ" left on the throttle lever. Then if i do push it the rest of the way the engine looses power down to about 4,000-4,300 rpm, then the rpm only climbs again when I pull the throttle back and start again!?

The cavitation plate is only 2"-3" above the bottom of the keel, which seems a bit low to me don't you think?

Where would you suggest I start? Change the prop for a smaller diameter or put a Jack Plate on to stand the engine off and raise it up?

Also i have a bow ballast tank fitted but no water inlet. Should i try filling it through the air vent with water to try and take some weight forward?

Thanks

Depends a lot on how much trim you are running to get best speed - as you go higher you will get less trim effect. But overall for speed I would hope on a stepped hull to run the engine higher than you have.

But if you still have throttle left and it is going out of rpm range you will need to look at more pitch (may only be marginal at this setting). Then if you go higher the rpm will go up and you should certainly look at more pitch.

Ballast all depends on the ride and amount of trim. But try to find a set-up where you are not having to trim far from neutral / level trim for best speed. So you can try with sand bags, water ballast, people position / whatever to learn from.

Thanks, Its all a bit of a learning curve for me. I'll try and get out if the weather is looking better tomorrow and see where my trim is at the moment for my best speed. Off the the top of my head, I don't think its far off level.

I assume you mean trim level neutral as in having the prop in-line with the keel?

As the engine won't go higher on its existing mounting holes ill have to get some sort of jack plate. If i am doing this should I go for something with a stand off? what sort of height should i be looking for for engine height?
