Is it safe to overprop a vessel for speed?
My 22’ pocket cruisers hull is 1900LBs ½ way loaded, w/ a engine pod setback 20”. Original engine was a 165 merc inboard out board 715LBs.
Engine swapped is a 2004 johnson 175HP.carbed 2 stroke 383LBs pod and brace90LBs w/ 14.25x 24 stainless steel prop I went 53MPH on GPS it got a tad unstable.
It was suggested to me not to use a high pitched 24 never got a full explanation why.
I’ve dropped the pitch down to 19” same diameter and do notice a drop off in speed but quicker hole shot.
Then tried a 14.25x21 aluminum slower than the 24 haven’t clocked speed yet but livable
So Is it safe to over prop a vessel for speed?or doe’s this over stress the engine?considering a 14.5x22 aluminum.
Thanks for advice.
