Backup Engine?

[GaryD]

Due to recent engine problems, im looking to buy a backup engine for my RIB. My boat already has an aux engine bracket, so all I need now is the engine.

For my 4.5m Narwhall RIB what size of backup engine would be advised, and does anyone have any recommendations on a make to go for?

I dont want to break the bank, so something cheap and reliable as a backup engine is all I am looking for.

Thanks in advance folks...

Yamaha or Mariner take some beating .I have a mariner 75 and a yamaha 4hp for backup . both very reliable.

Id say something 4 - 6 hp, a lil simple 2 stroke.

As a rule of thumb 1hp per meter seems to work quite well - 4hp should do.
