Hello, First time poster here! My brother in law has a Norman 18.5 with an old 30 hp. He is thinking of upgrading to a Honda 50hp 4 stroke. What cruising /top speed could he expect with the Honda 50 hp?
Hello John, I wonder how old the boat is? I'm upgrading from a 15 to a 50 myself at the moment. The answer to your question may be 20K for a couple of minutes until the back of the boat falls off... A 4 stroke 50 may weigh around 110 kilos... so your brother will need to assess the strength of his transom. There is a plethora of information on the site regarding the various ways of going about this. All the best Mo
Norman 18.5
