As long as the hull has the maxed out hp engine on it.... Ie: I would not buy a rig rated for a 150 with a 90 hp engine on it or anything less than max hp.
I say your best to wait till spring buy used. Because it sounds like your not quite sure what your after.
Oh and the 620 well your looking at creme of the crop there.
Sir I am sure you work to hard to spend so much on something that only gets abused. If it's more than 25% of your annual income don't do it. I would regret the payment I just signed up for.
New or used? That's up to you. I bought my last 2 boats new and the one before that used. The only boat I had real issues with was the one that I bought used. As far as the Princecraft brand, it's a quality boat. Yes I have looked into them. Their 22ft Platinum makes the Lund Baron look like it's for amateurs. Personally, I like the Princecraft Xpedition series for a pure multispecise fishing boat and the 20' model would do you well pulling tubes. A bit more expensive than the Hudson Series. I have to believe Princecraft has to have better pricing in Canada than Lund or any other American brand.
So, if you are second guessing a Princecraft, don't. If you are second guessing new or used....you'll figure it out.
Do what I did...find a demo boat and purchase a new motor. Best of both worlds!
I always buy used. Let someone else take the depreciation.
