I've got an 18ft Alumaweld Intruder 175 Sportjet W/14 Degree ........ Does very well in the Big Salt. I added some "Bolt on" Railings (a lot less expensive than the Welded Stock Alumaweld Rails ....They work great. Added 10.5 inches With some Gaps to get in and out of the boat. As for rivers ....It does great. Plenty of power. Have Run in as liitle as 8".
Gets on plane very quick. Boat sits at 2075 Lbs. with kicker, gear, and two 200 Lbs Fishermen. W/ 175 horses ...it flies.....
