HP ratings

Harvey, I can only reply for myself. The closest motor service for me of any type is 155 one way miles, so I have been forced to do my own maintenance other then for a few minor exceptions, making motor make, not all that important, also very little of my future cruising is planned for BC waters. With twins the Yamaha 60’s are 60 lbs heavier then the Tohatsu with the Tohatsu having more amp output. The Tohatsu seems to have an extremely good reputation as do the other major outboard makes at the present time. My present motor controls & gauges are 1999 era, so all must be replaced too. I’m looking for the best power to weight ratio & torque output over the rpm range with overall cost & fuel milage, the main other considerations.

EQ won’t presently mount the 60 hp motors without the factory upgrading to 120 hp, so if that doesn’t change & someone else will, with the sticker removed it will be considered by me.

Reading through these messages I see in some of them a similar thread. "Instead of 50hp twins, I want 60hp twins but the sticker says 115hp max" Or in the case of a single motor, "Why can't I have a 120hp engine instead of a smaller one"? In both scenarios the new generation more powerful motors are only a few lbs heavier than the old carb type.
No one has talked about the torque a more powerful engine(s) puts on the transom! My other question is......If the twin 50s or single 115hp will have you on plane at 28mph, why do you want more power? Is it so you can go faster and plane at 34mph? Just asking.
Also I don't think insurance companies like you exceeding the max hp printed on the sticker, or peeling the sticker off. Just saying.

Martin.

More hp for me isn’t about max speed of being able to do 30+ mph. I’m pleased to obtain 13 to 20 mph & 80% of our over 20,000 cruising miles in our CD 22 has been at below 7 mph. What I’d like to be able to do is place the boat where I wanted on waves for safety sake in rough seas, be able to plane if needed on one of the twin motors & when planing at 13 to 20 mph have the motor noise to be much quieter. How much more torque there is in the 60 hp motors & where it is in the rpm range is a major concern of mine. If the increased 10 to 20 hp is only available in the over 5000 rpm range, then I would consider it worthless hp for me as it’s only good for increased speed at max rpm. In the past I was told this was true about the Honda 40 vs 50. I’ve asked for clarification on this here in the past with no answers & Honda does not publish hp, torque & rpm comparison graphs, that I can find.

If the law doesn’t require stickers showing hp ratings for boats over 21 feet & several here have stated it’s not a problem, I highly doubt a 5 hp increase will cause any problems with insurance, especially with weight near the same & insurance notified when applying or in the motor change process.

Jay, I agree, the HP increase, if only in the upper RPM's would be worthless to me too. I would like the increased HP to be able to run the OB's at a lower RPM for the same speed. Much of my cruising is at 4-67 knots, and the higher amp output would be nice as well.

Thanks for the reply.

[quote="hardee"]I kind of like the idea of twin 60's but why is no one considering Yamaha? Harvey

Weight is the reason. twin 1 liter yamahas would be 500 lbs on the transom. That's too portly for a 22 IMO

You're right about service though. Down here on the Georgia coast, almost all I see are Yamaha outboards.

Interesting topic

Never bought boat insurance, luckily never needed it; props, maybe a skeg but that's about it

And somebody mentioned the coast guard

Do they check for such things?

...recommended hp vs what's on the boat

Can't imagine marine patrol or coast guard even noticing a 115 on a 22

You are right Martin. I can't imagine anyone operating or transporting a larger boat like a C-Dory without properly being insured with full coverage. Gary.

I carry 2 million liability. Always have.

Anyway, I like hearing that most of you don't think these boats need bigger motors

Because mine's only going to have a 75

and I'm trying real hard to even imagine a 22 foot boat with only a 75 Very Happy
