I'm used to seeing the tab motors inside the boat with either wires (for electric operation) or hydraulic lines thru the transom to the tab rams.
The pressure created by these huge surf tabs is immense so a different leverage point is needed. The engineers must have concluded that this is the most cost effective way to operate these.
It will be interesting to see how this new setup holds up which is now entirely outside the hull. Being that Cobalts are primarily fresh water lake boats is a good thing. Saltwater would eat those alive.

that was my first reaction too, yikes! salt water will kill that motor in no time.... but then I thought, well Volvo Penta decided to put the trim pumps on the OUTSIDE when they went to the new generation. So I guess they know what they are doing? lol

My guess is they can't put them in the motor box because of the ballasts. Just a hunch haven't seen one in person. Kinda feels to me they got the boat done and thought. Well gee look here Alex we can put tabs on this beaut.

I think this is a big update over the previous generation. I remember when they first released the R5/7 surf and you would see facebookers using those surf tabs as trim tabs at higher speeds and ripping them off.

Yes I can definitely see that being a reason. I was thinking they did it to make it even more modular. less issues for the boat manufacturers to figure out where to mount the trim pump and how to route the lines.

But man... I would have thought they would figure out some way to keep it inside the hull. I have never inspected them up close but are they a completely closed system now? where is the reservoir bottle? how would you top it off? Clearly I dont own anything new
