If the point where the cooling water is injected into the exhaust is less than 15cm above the waterline, then when the engine is stopped, there is a risk that cooling water will siphon into the exhaust system, and subsequently into the engine itself. Such siphoning may be prevented by fitting the V-ASD38H at least 40cm above the waterline.
The V-ASD38H is ideal for toilets or holding tanks which are installed below the waterline. Comes complete with a skin fitting, hose clamps, and 4m of breather hose. Features a hose connection to the outside of the hull. There is a constant bleed off of cooling water through this hose, whilst the engine is running. Can be easily dismantled by hand for cleaning.
For 38mm ID hose.
Let customers speak for us
Simple task to select and order from a clear and concise web site and in addition a Very prompt delivery.
Quick delivery. My first foil kite, well made and easy to fly. Handles gusty conditions and delivers a good amount of pull in strong winds but not overwhelming. Loads of fun for beach holidays!
Boots exactly as advertised in length.
Many thanks
Had a couple of items from Waterworld and both have been competitively priced and delivered in a very quick time. I'm happy so far.
Thanks for dispatching my goods quickly. All arrived as promised.
Excellent service and good quality items
Received everything quickly - item was shipped almost immediately. So Father’s Day gift was sorted few days in advance. The kite is also very good quality. My partner enjoyed it
Great price and delivered on time. I’ll use again! 👍

Had a great experience with this company, they supplied exactly what I was looking for - and it was a product I found difficult to source anywhere else. I'd highly recommend them.
