Superjet Hood Drains

I’m not sure if this works for a RN but I found that on my 1995 Yamaha Superjet my vent hoses on the inside of my hood no longer fit when running a Factory B-Pipe and a girdled style cylinder head. I could get the starboard side hose to clear almost but I still didn’t like it. The port side hose wouldn’t clear at all because of the Factory Pipe. I stumbled across a fix for these issues when poking around the plumbing section of the local hardware store. I found a 2” to 2” rubber 90 degree elbow and a 2” PVC 45 degree bend. Total cost was about $20 and the rubber hose came with clamps for both sides. When angled just right, these both clear very well in the engine bay and dump right in front of the flywheel cover and behind the fuel tank. I’m sure there are many ways to do this but this is quick and seems like it should work great. The hoses and PVC aren’t very heavy so I don’t expect much “flopping around” I’ll keep an eye on it and see. Just wanted to share Incase this can help anyone!

Nice idea. My RN didn't come with hoses so I used some flexible dust collector hose and used worm drive clamps to secure them. It's nice because I can compress them when not on the ski so the hood sits pretty flat, yet I have the option to flex and extend them as needed in the bay.

I've been informed it is ideal to have the vents reach the bottom of the hull. My idea was concerned with water coming in while upright, the problem is when the ski is flipped over, the vents allow lots of water in when nothing is there. I'm sure my idea will help and is better than nothing but I might also try jak4y's idea with the dust collector hoses. They should reach the bottom and I like the idea of being able to lay the hood flat.

The extended tubing also directs the water to the bottom of the hull instead of all over the engine and carbs.

I cut mine on my RN because it was pretty tedious putting the hood back on without hitting the front cowl. I probably cut about half the length and it goes on alot easier now.
