I have a yamaha 25 and am considering converting to gas (lpg) any body have views on the advantages or diavantages of this idea .the engin is a four stroke and I am aiming for one fuel on my boat
What size outboard would I require to power a 40 ft /10ft steel hulled flat bottomed barge for use on inland waterways only. A 4 stroke 20 hp yamaha has been recomended by the builder but I feel this is under-powered max speed on inland water ways is 4 kts the boat fully ladfen will way around...
