Welcome aboard, you've asked the quintessential C-Dory question!!!
Which engine to select for a new boat or repowering is probably the most debated topic on this site! There's more information already available on this topic than you can read in a good 8 hour day's work! In fact, some of us may be getting weary of posting on this topic! Rather than start the whole process anew and even be afraid we'd leave a few details out, the best place to begin would be to take the Search Engine function on the Home Page and start out with some of these topics:
repowering
new engine
new motor
motor selection
motor choice
single or twins
single vs. twins
(specific motor)- Honda, Yamaha, Suzuki, Johnson, Mercury, E-
Tech, etc. Might include hp rating, e.g., Honda 90, etc.
You might even try "Run Down Battery" the latest topic where the endless debate resurfaced, and look at the latest owners poll results!
By this time, you'll have a handle on the search process and a list of specific questions that remain unanswered.
Also, go to the Home Page, scroll down to the Library (technical topics), and find the section that deals with engines and the like and looks at the two pages of topics and just go shopping for information! Many of the topics that don't look exactly like what you're looking for are loaded with this seemingly unending debate on engine choice.
Also pay attention to the comments on dealer service, warranties, and the like that go beyond simple motor choice. HTH Joe.
