Hey fellas — I’ve been a silent observer of the board for some time and you’ve all helped me solve a number of issues with my old boat. I have a new-to-me Skeeter ZX225 with VMax 225. My first outing with it was on St Clair. It was “moderate” chop with 2 footers in afternoon. I had all kinds of issues keeping the bow down and the prop would bust free (cavitate) much more than I’d expect — and sometimes did that when trimmed all the way down i think. Porpoising was common. That evening I went to a local lake. Flat calm and boat would porpoise. It’s not a big lake so I wasn’t able to really try and get to WOT but at 25-34 it would still porpoise....and motor was trimmed all the way down. I didn’t really feel I could ever trim up at all on either lake.
I know there’s additional detail needed. I will measure prop height below/above pad this evening. It’s a 3blade prop...I’ll get more specs.
Its on a manual jack plate.
One other observation — it has a Lowrance total transducer mounted on a bracket on the jack plate. That would not read at speeds over 10 mph, which may also indicate motor is too high...
anyway, I’m going to try and debug it. With my use I don’t really care to go 75 mph. I do want to cruise at moderate speeds without porpoising and in big water I need to be able get the nose down as needed and, of course, to get the nice up when needed as well.
I have a 4 blade 25 pitch trophy plus prop that i could install. I’m not opposed to a quality foil if that’s a good option. I just want to minimize the porpoising and eliminate the cavitation....and i need that ducer to read. I realize it may not read at 65 but it should at 45-50. It did on my previous Champ 191.
