Suzuki makes an excellent motor, and as I have witnessed -- they honor their warranty agreements. However, if I had a choice for the CD 16, it would not be a Suzuki for the following two reasons: 1) it is a heavy engine, which weighs down the stern I believe more than its competitors, and 2) they won't let you install a hydrofoil on the lower unit. My 4 HP Yamaha kicker (which is a vital safety hedge) adds another 50 lbs. to the stern. Believe me -- if it would cost me less than $1,000 to swap my Suzuki for a Yamaha, I would do so today. However, it's not worth the thousand's of dollars in replacement cost. I'll wait for my warranty to end in 5 years, and then re-assess the situation.
On the other hand -- if I had a CD22 or bigger boat, I would prefer the Suzuki. I've read, and have been told of cases where Suzuki's have 4000+ hours on their engine without major overhaul. Do you know that they don't use a timing belt? They use a timing chain with an automatic, hydraulic tension mechanism. Try to get than many hours on a Honda or Yamaha!
Thanks!
