the correct prop.
My wife and I just got into Tacoma today on our new (to us) newport 28 mkII . We left Bellingham sat. at noon in a snow storm. We love the boat ,pretty much everything works,(it is a 1983 boat) My one area of concern is speed under power.We spent the whole trip powering, 20 hours total, as there was no, or very light winds.The boat has a 11 hp universal diesel turning a 12x12 2 blade prop. My question is should I be able to get more than 5 kts. from it on flat water? Anyone have any thoughts on this? thanks
