Thanks guys. So there are no vents anywhere. For some reason the old flat filter was removed and changed instead with the plumbing
pipes. My guess is that was because there was no ventilation so can put those in. I have no idea about the hours. It had a full rebuild
when I brought it and has done 150 hours on that. The guy that owned the boat before me only used it once a year whereas I am using it every week or so even in winter and a lot of distance as well. Is my first boat so slowly learning
all the bits and pieces. Really enjoy getting to know about it more and working out issues as they go, is heaps of fun being out.
Twinboat yes that is the same motor
, it has never gone to 3600. Used to hit 3400 and then got the new prop and did some hull cleaning
and now hits 3200 but goes much faster. The prop is smaller so I am sending it back for a change in pitch
which should make a difference.
