I did not receive the part ordered. I ordered a Victron Multiplus 2 and recieved vehicle floor liners. Customer service has been not completed the return of refund as of yet. I would buy from a reputable seller not here.
The Trident Marin Extra Flex Corrugated Wet Exhaust hose works great. I had to replace the old hose coming from the generator muffler to the exhaust pipe going out the hull. The hose needed to be curved and the flex was perfect. Delivery was fast with no issues. Thank you
