Mercury F30 EFI

I just took delivery of a new boat, a Mercury Ocean Runner 420 with 2012 Mercury F30 efi.

Didn't come with any owner manuals although I now managed to download those, now I'd like a service manual. Can anyone help out please?

I'll be able to decide if I'm going to do the servicing myself. Been unable to find when the timing belt needs to be changed, the motor has done about 90 hours. Why on earth should this info be so hard to come by?

IIRC timing belt is every 800 hours / 10 years and should be visually inspected on every annual service.

These are a non interference engine and if the belt breaks there will be no engine damage.

Normal service is annual / 100 hrs ..................

I have a 420 with an F40 EFI on the back an I am pushing 120 hours after 3 years use ............

Thanks for this Guru.

Incidentally what's the top end on yours? I regret not having the extra 10HP but I believe I got a good deal at 6.5K with trailer and instruments so I couldn't turn it down. I tried it today lightly loaded, two adults + two dogs and got 26kn @ 6000rpm, a bit disappointing. It's got a 11" stainless prop.

2 adults and all my fishing gear it tops out at 31kn ............ but the hole shot is impressive, a proper pocket rocket !

They are good reliable boats with no surprises in handling ............ a bit bumpy in a chop, but that is to be expected with a medium V hull. You will find it handles best with the engine trimmed in to keep the bow down.

I think 30/40hp refers to the 750cc engine, mine's the 526cc 25/30hp.
Thanks it's unfortunate.

Not sure your right there 25/30 = 526 40 = 750 and the 50 = 950 ish 60 probably the same might be wrong

I understand the early 30hp motors 1999 to 2005 shared the same 747cc (Yamaha) block as the 40hp and were easily uprated by changing the restrictive Bakelite heat insulator behind the carbs and the throttle limit stop. From 2006, battery-free fuel injection was introduced with the current 526cc Tohatsu-made motor.
