Who has these size motors? Or who has had had both? Are they both pretty good on gas? I don't wan't to underpower a boat. Have any of you guys underpowered a boat?
It would help if you asked about a specific boat and motor(s), because some boat perform very well with less than max HP some others don't.
I did have an underpowered boat. It was a 1991 Lund 1700 Pro V with a 50 hp Yamaha 2-stroke. It was rated for 60 hp, but was underpowered with the 50 because with 3 people in it if there was enough wind to make 2-3' waves it would not get up on plane going into the wind. Other than that it was a great motor and really good boat.
I was looking to re-power it in 2004, to get more power not because the Yami quit, but instead I bought a Ranger 618 Tiller with a 90 Johnzuki.
The Ranger was no race boat, but it was definitely not underpowered. With any load it would get on plane quick enough and had a top speed of 33-36 depending on load.
My current boat, a Skeeter MX 1825 with 150 Yamaha 4-stroke, is certainly not underpowered either. 5 seconds or less to plane and ~50 mph top speed. It is rated for 200, and with a 200 4-stroke they do about 54, with the 200 2-stroke they do about 57. To me the extra few mph isn't worth the cost.
As to gas mileage, on most boats you will not see any real difference between a 150 and a 200. According to Yamaha a MX 1825 with a 150 4-stroke will get just over 5 mpg at about 30 mph and about 3 mpg at 50 mph. |
