I currently have a 1978 Sceptre 23, single Mercury 200EFI on the transom. The boat is an original outboard boat. The boat is in good condition and underwent a refit in 2001. It was re-powered with the Merc 200 EFI at the same time. I have updated the electronics and some of the wiring, and the boat is pretty much perfect for my needs. Its small enough to tow long distances with my Tundra, small enough to fish inshore or on lakes - yet big enough to go offshore or cross the stream to the Bahamas. I live 4 hours from the ocean (Gulf) so I have to temper my desire for a bigger boat
Last season, I started having intermittent problems with the motor. Of course, the problem showed up when I was in Bimini Bahamas
At times, the motor drops 3 cylinders and obviously runs like sh$&t! All the motor vitals are good, but I have yet to find the root cause of the problem. I am a capable mechanic, and have all the necessary tools, but do not have much time and I would much rather enjoying the boat instead of chasing gremlins.
So this brings me to the repower. The transom and fuel tank are original, so I would like to redo those at the same time. I would really like to add a Hermco bracket and close in the transom for the added space and safety. At the same time, I would like to cut out the live-well (currently blocked off) and improve bilge access. I plan to replace the fuel tank and may even fit a larger tank if it fits, 140G like in the later boats for example.
The details of the future power bracket combination are a bit fussy. I need to decide between twins or a single and between a 2 stroke or 4 stroke. I like the idea of having twins for the added perceived safety, but don't like the added costs and weight. Whatever I do, I do not want to degrade the ride! It seems that modern outboards are pretty reliable so I am leaning towards a Suzuki 300, or 250. I am also considering an Optimax or an E-tec (due to less weight). Whats is the best combo? Braket for twins with a single 30" Zuk 300? Something else? Are twin 4-stokes (Zuk 140's or even 175's) too much weight? Whatever power I get, I may buy slightly used or new, depending on whats available at the time.
Thanks for the suggestions,
Mike
