Re-powering 1972 SeaCraft 23'...F300?

[kmoose]

I've owned both Yamaha and Suzuki 4 strokes and am much happier with the Zuke. While I have never required warranty work on either, Yamaha is stringent about dealer done scheduled maintainance and will deny warranty unless you drop bags of cash at the dealer to preforn unnessasary proceedures. The Zuke dealer I use could care less. He recommended Rotella dino 15-40 every hundred hours and I am still going strong with a 2004 motor with 1900 hours. Spark plugs and anodes are all I have every changed beside the engine and foot oil and a yearly impeller change I do myself. If you are handy enough to service your car the new 4 strokes are virtually the same.
