Hello,
My 19 Angler is powered by a 75 Yamaha 4 stroke. Also have a Suzuki 15 trolling motor. I find my 19 Angler is a little underpowered with the 75....especially when I carry 3/4 full fuel tanks for longer trips. As well as the additional weight carried in the stern from downriggers, big cooler etc...At slower cruise speeds , a considerable amount of trim tabs is required...at higher speeds , not so much.I cruise at approx. 16 mph at 4300 rpm. If I go to higher rpms it feels and sounds like the engine is "working " .
I see the 19 is rated for max 100 hp...is the rating based on hp or transom weight...or both ? I was thinking of repowering with a 115 hp....as the new engines are considerably lighter than some older models.....and then use a prop designed for initial power rather than top speed.....top speed is not an issue as my cdory pounds quite a bit in anything more than a small chop, ...
Any thoughts or suggestions would be appreciated. Thanks
 
i run a 90 etec. great power to weight. very light on the stern too
 
Without even reading the other responses, E tec 90 was first thing that popped into mind as well...great power to weight and torque, mine did wonders on a previous boat with similar characteristics as you describe.

Also, if you are considering 115 and don't want to exceed the 100 hp rating take a look at the new Mercury Command Thrust 90, same block as the 115, runs a lower unit from a 150, and swings a big 15" prop. Probably heavier than the Etec, but the performance might make up for it. I've run both and love them both, but for the 19 I'd probably choose the Etec due to the light weight.

I also would go with the E-Tec. I think that it matches up very well with the 19.

I've had two CD 19's. One was powered with a Suzuki 90, and my current boat has an E-Tec 90.

The E-Tec holds the boat on plane through a much wider speed range, it is more responsive, and it gets a bit better fuel economy.

Doggyjazz: thats interesting. My Yamaha F80 doesn't feel underpowered at all. I guess the bigger block helps.

The eTec sounds like a good move though. How easy is adding the oil these days? Is it oil injected or do you have to add it to the fuel?

On the 90 the oil tank is mounted on the powerhead, just remove the cowl and pour it in, easily done without any funnel. I ran the more expensive XD100 on mine but it just sips it...I think I only went through 3 bottles in the 5 years I owned it (granted, I didn't put a lot of hours on).

I thought the Yamaha F80 "became" the F75 because they changed the rules about how horsepower is measured/claimed, or something like that. (And the F100 became the F90.) Chris from Rana Verde has a 2003 F75 and it's seemingly the same engine as my 2002 F80. At least as far as I know (?). I even think the F80/F75 use the same block as the F100/F90, but are just de-tuned.

I do believe that in 2005 Yamaha went from carbs to fuel injection on the F75/F90, but you'd think that would make it peppier if anything.

Sunbeam-

I know they changed the rules back there some years ago to indicate the HP available at the prop shaft instead of at the power head, which may account for the differences you're discussing.

A 5-10 HP drop down from the end of he crankshaft to the end of the prop shaft would seem about right for such a difference on an engine of that size range.
