should be fine i mean they run just fine in a buggy or truck with air filters. the only thing is that most people willcomplain about a boat not really needing one since there is no dust or dirt on the water. the way i figure it, a little castor oil on the filter will stop the water scince oil and water dont mix, i plan on using one on my boat.
