I have an umbrella press, maybe I could print them up as an Aerotec accessory .

Sounds like (lately) the best Areotec accessory is glue! :-)

Do bear in mind all I know is... 1) my Suzuki 20 doesn't splash at a low transom raiser height which would have caused the Mercury 15 to splash loads... and 2) my Suzuki has a much larger anti-ventilation plate plus a larger upper water deflector plate.

I don't know which of the plates being larger is making the difference... if it's the upper plate that would be far easier to enlarge.

Aerotec transom splash issue.

[QUOTE=SeanKent;710875]

Hmm all this messing around with engine height does put me off a bit.



If I do manage to get an aerotec, I'll be looking to pick brains on here as to best way to deal with the splash.



Hi Sean,
It's not only Aerotec's that require tweaking engine height and trim.....all boats benefit, so don't let this put you off one.
As mentioned previously, we seem to get best results with AV plate about 10mm below keel. High enough to reduce drag from lower leg but low enough to limit ventilation to occasionally out of tight turns. Good for us in swell and chop, two up and often towing kneeboard or wakeboard.
Really is worth all the faffing, and you only have to do it once. Best and most exciting method is to hang over back of transom at WOT and look at water flow over lower leg / AV plate. A Go Pro on a stick also works, but much less exhilarating!
A few combo's here all with same 20 hp Suzuki motor.

Aerotec 365 (current stubby cone 380)

F-Rib really easy to set up as very clean/consistent water flow off hard hull.

Chipko great images to assist. When you say trim 4 of 5 with the Suzuki/Aerotec combo... is that 4 of 5 trimmed into the transon or out?

Fenlander, position 4 of 5, away from transom. Works OK on 3 also, so if there was a 3.5 that would be perfect.😀

I didn't mess during our first running in trip but something I'd forgotten to comment on in my report on the engine was that the Suzuki felt far heavier on the tiller than my old Mercury so I wondered if a trim change might help?

It was set in mid position.

That's interesting. Not noticed this on different trim settings, but must admit I prefer some steering friction so have dialled this in on the adjustment nut/lever.

Just diffeing preferences between us I guess. I don't usually have any steering damper on and like a free under the fingers feel for an outboard. Despite being free at rest with the damper off my Suzuki feels a little weighty under way.

Maybe due to the 33% additional power and the added weight?
