Hi Playtime, Firstly congratulations on your new boat.
I own the Tournament 1900 & 130 Etec that Rando has mentioned.
My experience of my boat and motor combo is in comparison to a friend that has a 2000 tournament with 150 Etec. The 1900 is basically the 2000 hull shortened by 300mm with a 1750 cabin on top. (so I'm told).
The 1900 goes great with the 130 but I have found that the 130 is revving harder to achieve a similar speed to the 150, this in turn means the engine is using more oil (XD100) because it is closer to the higher end of the rev range.
Now the obvious response here is don't rev so hard, but reality is that on a great glassed out SEQ day it is pretty hard to keep your speed down to 25mph when you can easily do 34mph.
The etec has, as i guess many new engines and guage combos have, a nifty display that gives fuel consumption in Litres p/h and speed, with my setup between about 24mph and 34mph fuel consumption(lph) = speed, above 34mph fuel usage is significantly higher.
A comparison of the 130 to 150, 4 cyl 1.7L v 6cyl 2.6L (approx), next the gearboxes are different ratios, the 150 turns a greater pitch prop easier, this is where the 150 can cruise at a same speed with a lower rev, thus using less oil and fuel. Trolling and low revs there is no difference as the quantity of oil injected is dependent on the engine revs.(revving harder = more oil used)
My friends boat seems to cruise at a similar speed without working (revving) as hard.
I have tried numerous different props, both 3 & 4 blade different pitches and sizes, with results ranging from incredible hole shot but a significant loss of top speed, (8 - 10%), this also gave a lower cruise speed at the same revs as the original prop.
At the time of purchase I discussed in detail with the salesman about getting the 150 and was convinced otherwise that the 130 was more than adequate, now with the benefit of hindsight I would definitely have gone the 150, especially at the time it was only an extra 1 or 2 thousand, I cant recall exactly.
I'm not familiar with the Galeforce nor claim to be an expert on etec's or any engine, I'm just passing on my experiences of my boat and motor combo and my observations and results, and I hope this helps.
Summing up - I love my boat
