Here's a plan pic of the plate (click to get full size and then click on + symbol) - to get the exact template size you will need to print on paper/card and test fit first but approximately 205mm at the widest point of the outer perimeter:

Thanks Max. I'll make a card template from the image and refine that to be as as tight as possible to the leg before I cut the ply.... mind you I think our outboards will be identical.

Did you make one? I lost mine today somewhere past Beachy Head. WOT run for ages in the waves then noticed I had very wet feet and the anti splash plate had gone west!

No Max it's on the to do list!

It's been a bit frantic since that holiday period of ours some two months ago when there was much discussion on here about the splashing... but now we are down to one outfit I can concentrate a bit.

Perhaps a combined transom mounted anti-splash plate and sonar transducer mount!

I racked my brains about mounting one on the transom but despite looking at it from every angle could not find a way to do it without drilling the transom (even more than it has by previous owners for rod holders etc) which I really did not want to do.

Judging from the ridiculous amounts of water being thrown up once we lost the plate it certainly did a reasonably good job but far from perfect and it did just deflect most of the splashing backwards.

Made no difference to speed but as mentioned before I've been a bit disappointed with our top speed in the 380/Merc 15 - really about 16.5 to 17 at WOT when I would have hoped for more. We're not heavily loaded, maybe 160 kg (350 lbs?)

the relatively slow top speed was why I never kept the one I was trying out (a very trusting seller let me have it for a weekend to see if it suited me ).the same 15 hp mercury on the honwave 3.2 airfloor I bought saw over 22 on the gps but on the aerotech no more than 16

Wow, that's a huge difference - I know the Aerotec has a 'draggy' hull but 22 kts on a 3.2 with a 15 is superb. Having said that top speed would certainly not be the deciding factor for us in which SIB to go for.

We've hit 18 in perfect conditions occasionally but not as a constant.

wasn't knots max I regularly got 22mph 2 up on the ski section across loch ken which is a little choppy .if I went out when it was mirror flat on my own 24-25mph was max couldn't do it in the sea tho unless it was flat calm and I never saw a flat calm sea in it.this was on my garmin plotter fishfinder

Just keeping to kts for simplicity (converting beerbelly's figures)...

So Max you're seeing 17kts as a maximum that's reproduced consistently each time you're out??

That does seem a bit down given I'm getting 17.9kts two way runs in a chop with a greater load than you and an 18.6kts with lightest load which at me plus small teen would equate closely to your load.

I don't have a tiny tach so there is just the possibility my motor is revving higher... knowing your boat will be properly inflated the only other factor I could think of would be prop condition... but I guess yours is near new and all shiny black paint like mine... same 9" pitch too??

Beerbelly in kts you're getting 19.12kts on the 3.2 Honwave (your choppy water reading which was my sea condition and I think Max's usual too) which is near identical to the 19.1kts I was getting on the flatter air floor Zodiac 340 Acti-V I used in the same period on the same water as the Aerotec tests.

The Aerotec speed on your test converts to 13.9kts. There was clearly something wrong with the setup or measurement because over the ownership of many SIBs I've found with a properly inflated lightly loaded SIB the speed is pretty consistent across makes/types when used with the same Mercury/Mariner 15hp 2-stroke outboard... usually within a kt or two... never over 5kts down. As an example of this consistancy a figure I have logged back from 2011 is a Zodiac 360 Acti-V with a light load max of 19.9kts on fairly flat water with the same 15hp.

Sorry Beerbelly, convention on here is kts so I presumed that's what you were talking.

If you were getting 14 or less on the Aerotec with a 15 then as Fenlander says something was wrong!

David, my (your) old Fastroller 340 with a 9.8 did as well as the Aerotec with a 15.

I did set up my 15 with a tiny tach but it's kaput now. At the time I think we were at 5400 or similar but I'd need to check that. Engine runs great, prop is near mint, pops up on plane. Is there anything else to suspect if it's down on power? Would it still reach max/normal revs at WOT?

Impressive steering wheel, I must try it in the future with my Aerotec 380

Knocked this daft wotsit up quick as being able to pull the BAT up the beach with two people, one hand each - with a solid connection is much easier. The BAT lacks front bow side handles and having tried a bridle rope it never worked very well.

Wonderful aerotec

Hello everyone

Here is the presentation of the improvements made to my second BOMBARD aerotec 380.

I kept the first 13 years old and the last one was 9 years old. I do not regret my choices and the next will also be an aerotec. I rent a bigger boat for long walks when we are many.

I go for walks in the river (ex Paris and these channels) at sea (Corsica and Pyrenees) on the ocean (golf Morbilhan) of the scuba diving, ski nautic.

The best compromise not to break the bank by having a boat.



Aerotec 380 improvements

The front bag attachments are not strong enough.

1. Fix: sewing large straps

The knurled nuts (Emile Maurin) of the fixation of the bench rub and damage the fabric of the flanges.

2. Corrective: placement of rubber band (no bonding).

Premature wear of the aerotec mat on sufaces in contact

3. Fix: Protection of the aerotec carpet with a carpet TAPISUM style that I coated with a soft sealant to make it resistant and protective for the surface in contact with the aerotec carpet.

4. Patch: Added piece of inner tube with the part of the mat in contact with the transom.

Excessive stacking with the motor

5. Fix:

· Flat addition on the transom to avoid stacking.

· Flap attachment on the motor to reduce stacking.



6. Installation of a DEEPER sounder attachment (bluetooh) on the rear flap.

7. Attach a compass to the bench.

Engine with HB SUZUKI EFI 20 AES, engine with the best weight / power ratio of the market. (a little expensive) but a breathtaking consumption (10 times less than the DT15C SUZUKI-2 time).

Nanny 25l For very long walks.



Diag SUZUKI kit for engine maintenance.

HPA brand waterproof bag

VHF portable ICOM brand ic-m35.





Evolution under study

Laying foils in order to hover over the water.

See boat ZODIAC 5.50 semi rigid equipped with these foils on the net.

Interesting to read of your experience and modifications Nevada.

Did you put that anti splash plate on the transom when you had the 15hp outboard? I have found almost no splash with the Suzuki DF20AS.

Non pas besoin de flap avec le DT15C.
