This is a question mainly aimed at other Marlin owners.
I have a couple of dislikes "so far" with the Marlin 2. First one is the position of the exhaust outlet, On mine it exits vertically into the rear of the thrust duct. Just seems a silly position due to the fact when the hovercraft is sat out in the rain, there is a potential for water to run down into the engine cylinders. This is an easy fix just by bolting on a 135* stainless steel bend, which is on order. The exhaust is remarkably quiet though, so that is a positive, just seems strange that it was left pointing vertically where it can fill with rain water
My biggest concern though is the position of the air filter, the air intake is only about an inch from the floor, it wouldn't take much rain for the water level to reach the air intake if the hover was parked slightly nose up, or even a small wave splash over the hull while flying. I want to move the air filter, so does anyone have any ideas of how & where to place it?
I haven't looked yet to see how practical it would be to mount it just above the engine cover, but that's where I'm thinking it would be better placed " in the air flow and well above the floor", or the other option is alongside the duct cover, but that wouldn't look too pretty. The reason I am so intent on moving the air filter is I mounted one that low on the freedom one I built many moons ago, and I had loads of hassle with water getting into the carb.
While I'm at it, any other upgrades I should be doing while I'm in the mood to do them?
