I have an older 19' Almar (aluminum) boat with a custom hard top. It has a 130 hp Yamaha Saltwater Series 2-stroke prop on it and was wondering if a 90hp fourstroke prop would be enough to get it on step with a few guys and possible moose on it? I mostly use it on the saltwater but plan on hunting the Yukon one of these years. At this time, I don't plan on running a jet on it but I guess you never know... The 130 Yamaha will push it over 40 mph, presently I cruise at 3700 rpm, around 27 mph. Thanks for any input or experience anybody may have in swapping outboards. Also, does anybody know what kind of value a 1996 130 yamaha s.s. has? Thanks.
