23" Scepter I/O performance

the multiport engines are definatley the way to go - smooth acceleration,"turn key" starting,alarm systems keep the engine from self destructing...

last volvo repower i did - the distributor had a "left over" 5.7 gxi engine - i got a deal that was hard to beat.
i'm not a fan of replacing "long blocks",or rebuilding what's existing - i use complete "drop in" engines...reason being,you're pulling an engine that's basically worn out - the exhaust system - manifolds and risers,tin ware,pulleys,fuel system parts,electrical parts - these are all old too...transfering these old parts,onto a "rebuilt" block,or,replacing these parts and installing them onto a "rebuilt" block - this all starts to add up,and,in the end,you're got a "rebuilt" block - most of these blocks carry a very limited warranty.purchasing a new,drop in engine,it carry's a mfg's full warranty,it's new,as in new,everything on the engine is new,and,in most cases,it actually works out to be only a few dollars more.the idea of a repower is to "up grade",make the boat perform better than it did previous...
for what it's worth: the multiport injected engines have proven to be very trouble free - i've repowered numerous boats with these engines - no failures on any...

my own potter built -
it was repowered in '01 with a 5.7 merc magnum MPI with the horizon package - bravo drive.that package has proven to be incredibly efficient,and reliable - ZERO problems - cruise speed,with a full load - 150g fuel,loaded to fish offshore for the day - 22-23kts...that rig's been ran and ran hard...
