For Josh about my Bruntons Autoprop. It is the 3 blade H5. It was on Alianna when I purchased her in 2005. So far i have replaced the hub zinc once that’s all in 15 years of use in salt water. It is powered by a Universal M4-30 and has strong reverse and powers Alianna a 35 MK2 at around 14,000 pounds loaded for cruising well into seas and wind. I sail with the transmission in forward and i can see a half knot or so speed increase when it is locked in forward, for example from 6.4 to 6.9. I can use that as a “passing gear” so that boats getting passed don’t know what happened All of a sudden like. lol. And it is very quiet.
