85 HP Evinrude Question
Hi Guys,
Just after some advice from the all knowing combined intellect of the group.
I recently purchased a Chivas Thunderbird MkV that is fitted with an Evinrude 85 hp motor that was manufactured in 1975.
The motor is is excellent condition for it's age and has plenty of grunt but running at about 15 knots it uses 25L/hr which seems a bit much.
Is the fuel usage normal and if so should I stick to this motor or get another one? If replacement is warranted what would be a suitable size motor and price ?
Thanks in advance.
AG

Re: 85 HP Evinrude Question
might help us mugs if you say how heavy that boat is, what diameter and pitch prop, and whether 15 kts = wide open throttle, half on the plane, etc etc.
Gurus will know the answer on the info you have provided, no doubt.

Thanx Fishtime for replying.
I thought that the old Chivers Thunderbird was a boat common enough to be known to most ,sorry
In answer the TBird is 18 foot 6 fibreglass and is HEAVY.She is capable of 35 knots at full throttle so at around half throttle it uses 25L/hr.
Have no idea of prop pitch but the motor etc are standard issue for the old girl.
Thanx again
