This will be year 11 that I have owned my Striper 2101 and knock on wood the 4.3 GXI motor has been fantastic. The only thing to have failed was the alternator last year, other than that its been only oil and filter, spark plugs ,rotor and cap. I am pretty anal about flushing and after taking apart manifolds 2 years ago they looked brand new inside. The motor pushes the boat 30 mph cruise and 47mph on gps. The SX1 leg has also been mint without any leaks and the boots look new, lots to be said about a trailered boat. I can do a Thrasher run from McDonald Beach return for about $120.00 including trolling with Yammie T-8 for 2 days, I never have used the main motor for trolling.
