That range!!! I do like to go long but only get 1.1 mpg. That’s why I squeezed a 130 gal tank in her, and still take jerry cans. When the time comes for repower, Diesel will be on the wishlist for sure. The boat performs great with the 305 but range is priceless.A buddy of mine has Volvo Penta in his 24 flybridge, he get 3+ mpg - and has over 2400 hrs on the engine - Great little motor that’s last him over 20 years.
On gas or diesel I recommend putting it away with a full tank. The reason is the more air space the more condensation. Additives give fuel the ability to keep fuel fresher and absorb some water.Its not only about range - gas vs diesel, right? Gasoline degrades over time, the amount of fuel to CAT or SCI is way more costly per trip - Gas is combutsable and likely to lead to fire if there is a leak, especially with jerry cans onboard - Go to Ensenda and they dont sell Gasoline in the marina. Not too meantion Gas engines will maybe get 500 to 800 hours before a top end rebuild (diesel engines run 3k rpms while a gas is running 4k plus rpms) Talk about realiability, a diesel engine doesnt need a altanater to keep running, once the motor starts - its likely to get you home even if a with a bad valve/cylinder. A diesel engine is costly to obtain and repair, the longeivity of a diesel (if taken care of) and cost to run a diesel far outway the lower cost of a gasoline engine, in my humble opinion.

Also water tends to sit on the bottom and algae will form between the layer between diesel and water. This also produces an acid that can damage aluminum tanks.
Nick Adams and I were driving down the freeway to pick up a boat we just bought. We were having a conversation about why we only sell diesel inboards and as we were talking we passed a ProLine that looked like it was almost blown in half and burnt long passed repair.
It was an outboard and a good brand of boat but boats happen.
I prefer Diesel for safety alone. Outboards for now have to be gas but more companies are developing clean burning outboards.
