Help with small outboard info
Recently bought a 3.8 m fiberglass sailing/rowing dinghy, [url=http://www.boatsales.com.au/features/2008/runabout/feature-classic-dinghies-10803]Feature:,weight around 50 kg, and want to buy an outboard auxiliary to keep peace with the partner and to use for fishing now and again. Options are 2.5 HP at 16 kg and 4 HP at 21 kg. The 4 HP would be sure to handle a bit of chop, a headwind, and some tide, but the lighter motor has obvious appeal if it's hanging of the transom when sailing, and for general functionality.
Could members help me with their experience/knowledge.
It also appears there are formulas for hull speed prop pitch/diameter to ensure the engine is able to operate at maximum efficiency throughout the rev range. I guess the engine dealer will be helpful with this information but any independent advice would also be welcome.
Looking forward to hearing from forum members.
