Aaron just woke me up with an email.
Sweden Calling:
I have my Magnum 27 from 1972 powered with a single engine.
496HO with Bravo One.
425hp
X-mounted as high as possible
Prop: Mirage 23 55 knots=63.4mph
Trimmed maximum on flat water.
Today I use a 4blade bravo 22 for a smoother ride.
(The children wants to wakeboard)
After installing the engine in normal position in run very nice in the water but did not have the top speed as mentioned above.
With the new x-mounted installation its faster but the ride in the water is more nervous. Tight turns is not possible, the prop is cavatating.
Otherwise - I am very pleased with my single engine setup.
If I drop something in the engine compartment - I can pick it up the same year.
The thing with Magnum 27 is:
You can go fast in any water condition.
It turns heads.
It handles very nice in the water.
About the hull number - I found my number on more than 10 different positions.
On the wood on the backside of the "cushions" close to the passenger seat.
On the wood on the opposite side of the "hatch" on the floor. (Under the carpet)
Inside the cock pit (Steering Wheel / Instruments)
And most af all:
Good luck with your work. Take many pictures.
