Here we go again . I have a 90 HP 4 stroke (carb 2003) on a 97 aluminum runabout Am looking at buying a Whaler montauk repowered with a 2005 90 HP 2 stroke. Which engine is worth more? Is it worth moving the 4S to the whaler or will the extra weight be a problem. No problems with either except annoying lower unit rattle at idle . I,ve used the search and read lots and want an opinion from readers.
