Hey everyone new here, and not sure if i should post here or the toon section, but hopefully i can get some help. I have been handed down a 26' toon of an extinct make, i guess its a western boat but have had trouble finding any real info on it. Im haveing trouble with what i would call prop ventilation as when im boating through out the rpm range i will get random rpm spikes and it feels like it looses grip/traction. It has a 1983 evinrude 115 2 stroke with a long shaft (20") and i am running a 13.25 x 13 4 blade solas prop. The engine is as far down as i can get it without adding a 5" extension but is, as i see it, still sucking air. I think i need to drop lower in the water atleast an inch but the local boat shop is trying to tell me that my pitch is to aggresive and its taking to much bite which is why it sucks air. I am rebuilding this toon and sadly dont have a working tach so i cant say what rpm at any point from slow to fast but i feel the "ventilation" in mid to high rpm and when turning at low/mid speed. I can definitely feel when the prop bites cause the 115 will really start to push the boat enough that everyone not ready for it has to grab some footing. From anyone that knows better then me, which is most of you im sure, does this sound like a pitch problem or a depth problem?
this is the best video i have of the last time i took it out for a test run, running at about wot i had to trim all the way down which plowed the bow and it gets some serious spray, worse then what is in the video. In my mind trimmed down and still venting i feel like i need to be deeper but could it be as simple as a bad prop choice ?
