Hello new Bombard 380 owner

Hello to all

Just acquired myself a mint condition bombard aerotec 380 with a yamaha 25hp motor.

And hope to be careering around the solent and south coast in the near future.

Got a few questions already on the subject of the boat so I'm off to pick the brains in the sib section.

welcome - i was playing with my aerotec today and it flies with an 18 on the back even three up, you'll have a blast with a 25! if you don't have them already consider getting some launch wheels fitted to the transom, they make the boat a pleasure to launch and recover even single handed. most of all, enjoy!

Yep launching wheels are high on my list as I have taken the boat out twice so far over the wknd.
And launching solo is a lot harder without them even with trailer
Been mostly out playing with the trim on the engine and also height to try and dial it in.

Also maybe going to put an extra seat in back towards the engine as the tube or floor seating gets really uncomfortable after a while.

But had 21 knots out of it today on a gps speed run

Nice outfit

Like the outboard stand not seen 1 like that before but I have led a very sheltered life .

In my humble opinion depending on what payload, how loaded, propeller etc, you should be getting more that 21 knotts, this is based on my own setup 3.8mtr Humber with Mariner 25hp 2 sroke wooden keel, wooden floor, Hypalon, 200kgs load excluding engine and fuel 25 knotts GPS in chop (scary) and 13" prop and only making 4,800rpm (I know its not optimum) still more testing to do.

Good luck

Yeah I thought I should have more speed going by what a lot of people on here say they have with there 25hp.
I weigh about 88 kegs then I also had about 50kgs of ballast up front just to keep the nose down a bit more and make it more realistic when the missus is in the boat with how it sits.
Then probs about another 20 kegs with fuel,flares,small anchor,paddles,VHF etc etc.

So not massively overweight but I had the engine trimmed all the way into the transom this time.
Because before I had it on the third hole out on the trim and I was getting a large rooster tail and the prop was loosing traction and over revving the engine.

But may try hole 2 again as I tried this before and it felt very sketchy at full
throttle but may be just due to being first time I ever took it out.

Quite a few people including me have raised the transom to stop the water spraying up!

Yep tried that also on Sunday just lifted the engine up as far as it would go to see if it would reduce the wash against the transom.
It go that bad the water was forcing itself into the bilge drains past the rubber diaphragms and filling the boat with water.
Did not get too much splash over the transom though but even with the engine trimmed all the way in it was still creating a rooster tail.

But going to clamp the gopro camera to the transom and film what the engine is doing while going along at different trims and heights so as to try and tune it in.

Bit hard to look down there and stay in a straight line while booting along. Lol

Yeah it's a nice light indespension trailer with rollers and the previous owner made the wooden mount so you can transport the engine on there than putting too much stress on the transom while on the road.

Plenty of good people on here with alot more experience than me (as long as the trolls dont get you first) but start with engine height, cav plate level with bottom of transom, like you say a video of what is going on whilst at full tilt would be handy, but I do agree that at full tilt it is difficult to have a good look without the possibility of loosing control.

Cool that's my next stop in sib section with lots of questions.

I reckon I'm going to possibly go and get a steering setup though as today I'm in rag order my arms,shoulders,back(spine) are all aching massively not felt this bad since doing motocross.

Just could not find a good place to sit or kneel as the riding on the tubes feels to sketchy and sat on the floor you just slide around
