Prosthetic valvular endocarditis (PVE) develops in 2 to 3% of patients within 1 yr after valve replacement and in 0.5%/yr thereafter. It is more common after aortic than after mitral valve replacement and affects mechanical and bioprosthetic valves equally.
Ray-my buddy has a 20ft Aquasport with a 115hp on it and it gets up on plane nice and rides real nice (200hp is way overkill for that boat-nevermind gas prices!)I really like his boat, it is a bit much for one guy to handle trailering, launching,etc. but besides that good boat!!he 20-foot aqua sport is a nice ride. I looked at almost every boat in the 17 - 20 foot range. Two points I found, Boats are a matter of opinion so get the one you like, and don't buy used unless you need to for $. I would sacrifice a used upper class boat for a brand new mid to upper class boat.
Take your boat weight and divide by 50. So, a 1000 lb boat (boat, motor, gear, passengers), flat bottom or still water would take 20HP to plane. If your boat with all gear is heavier, it will take more HP to plane.If your boat has a v-hull, it will take more HP to plane.If your boat is in rough water, it will take more HP to plane.Note: this is only to plane, not run around at 30 MPH. So, let's look at this. You have an aluminum boat that weighs 450 lbs. You weigh 250 lbs. You carry 6 gal of gas (total weight approx 48 lbs).This is now a total of 750 lbs. You will need a MINIMUM of 15 hp to plane. So, you stick a 15 hp engine on it and you are happy.ou have an aluminum boat that weighs 450 lbs. You weigh 250 lbs.
