What size? - currently have 80Hp, but probably don't need that much, so open to guidance
What gearbox? - options are either PRM or Technodrive... don't want a Hurth, as i've had problems with them in the past
Where are the ancilliaries? - can I get at the impellor when the engine is fitted?
Will it fit? - is the engine space sufficient
Is the alternator big enough?
Do the bearers angle the engine too much, and i'll therefore need a header tank?
Is the calorifier above the heat exchanger - again, will I need a header tank?
And then, do I do the install myself, or get it done professionally?... I like the idea of getting into the engine compartment and cleaning, painting etc.... so may well remove the old one myself... but installing, aligning etc would be nice to be done by a pro.... but can I justify the cost?
And what about where it is done?..... can it be done at Shotley?... or do I need to move the boat?... how, with no engine?... can I get it started long enough to get her down the river to the Beta or Nanni agents, or will Shotley supply and install at the right price?
I've asked for quotes, but quite a few decisions to work through!
