I have a 05 crestliner sport angler 1650 with a 90 carb Mercury 4stroke. You will really like that boat. Great ride comfortable for 3. You can go anywhere with it. Mine will run 40+ mph with 2 full tank gas and gear but I don't rev more that 5200 on purpose. It's an 05 and 2 mph makes no difference to me at that speed vs the increase rpm. Just got a 4 blade 19 pitch prop this year. Much better acceleration and keep same top speed. The boat has much greater capability than the current driver (me) as I have been out in Lake Ontario 4-5 foot rollers with no issues.
Enjoy the new ride!
