Author Topic:   Whaler Capacity Plate

skred posted 10-07-2013 10:15 AM ET (US)
My recently-acquired 1987 Sport 13 has the following specs: 1987 Sport 13, ordered with simply the thwart seats. The capacity plate rates the hull for 20 hp. (no navigation lights, rails or other accessories). I am renovating the interior as a console model. This may seem a facetious question, but do I have to be concerned that the 35 Johnson I have installed is going to somehow conflict (insurance or authorities) with the 40 hp rating that the console models possess?

No, I personally would just get the proper decal from Janis at Magic Brush to reflect your change from a tiller model to a sport / super sport.

Jeff, I would certainly do that if I find it is necessary.

Am I to understand that if I need a new capacity plate, say one that adds 25-50 more horsepower in a repower, this is a place that will help out?

My request stems from the fact that Whaler rates the 1978 Sport 13 tiller model for 20 hp maximum, but rates the console-steer models for 40 hp maximum. My boat was manufactured and sold as a tiller model, and I'm re-doing it as a console-steer Sport 13.
Your request sounds like you simply wish to change the maximum hp rating on an un-altered boat. If that is so, I don't think that that action would fall within what I consider "legal" guidelines... IMO

Well darn, I was hopeful this was a way a few forum members could get higher capacity plates including me for a higher repower.
I boat at 4-7000 feet in elevation and the power loss is probably about 20 percent. Everyone drops a size in pitch in prop size to compensate over sea level settings.
Whats most interesting to me is that I could put a E-tec 300 on my Outrage 20ft to replace my 225 outboard and the 300 outboard would do up here what the 225 would accomplish down there at sea level. That's it
Oh well.
Whats puzzling is that the rules don't seem to apply to stern drive boats. My neighbor has a 21ft searay with a 385 sterndrive by Mercruiser. Those horsepower numbes would never happen on a 21ft Whaler.
I see no max hp capacity plates on stern drive boats. I think they just get a pass

And how about power ratings on PWC's?

I believe since 1960 the USCG requires capacity plates on any and all vessels 20 ft or less. Above that size it is a manufacturers option, and in my opinion it is prudent for them to do so at least up through 30 feet or so. There is also a difference between OB, IO and inboard propulsion. The IO and inboard have a lower CG and therefore slightly better balance. Hence your BW has a capacity plate and the SeaRay doesn't (better manufacturer thinking)
I like the European standards which give different capacities based on where the boat is used. Off shore has a much lesser rating than inland lake/waterway.
You might have 27 people on board while docked in the marina on a 34'Silverton but you don't take that many out on Long Island Sound as was evidenced July 4th, 2012 when one capsized and lives perished.

As a kid, my parents bought a 1978 13 ft super sport with a 35 hp. After a few years the cable steering started to fail. I removed the console, moved the seats back, and used the tiller. I thought the boat had more room and a better ride. My brother complained about the steering effort. The boat now has a 9.9 Mercury, just enough power. It is interesting that the tiller models had a significantly different hp rating.

The 18 GTX is the same hull as the 18 Outrage but has an IO with more than the 150 hp rating that the Outrage has.

Onlyawhaler,
Change the sticker package on the outboard, in FL they have lakes that only allow 25 HP, and most people with 30's or 40's just change the sticker.

Maximum horsepower ratings often seem arbitrary, capricious, and totally illogical.
I often wonder if it is illegal to alter/replace the ratings assigned by the manufacturer.
To the CIA/NSA: if this post is being monitored, the posting above was purely hypothetical, and in no way represents an intent to violate any national, state, or local laws, regulations, or statutes.

I think the Maximum HP Ratings for the classics are spot on.
90 HP = perfect for the classic 17.
70 HP = perfect for the classic 15.
40 HP = perfect for the classic 13.
20 HP = perfect for the classic 11 with steering.
In fact, many of these work well with much less HP.
The Post Classics are another story because they are so heavy.
The new 170 Montauk is 500# heavier than a classic Montauk, but both have a 90 HP maximum HP rating.
