The Honda 135 and 115 weigh the same: 478 lbs. Unless you have the long shaft, then it weighs 485 lbs. Both engines are based on the Honda Accord 2.3 liter 4. In addition, the Honda 150 is the same engine as the 135 except for variable valve timing. They all run up to 6000 rpm so you can't run any faster..
Since a Honda 115 is acceptable for a c-Dory 22, I would imagine that a 135 is too. The only question is if you can keep your throttle hand from getting the engine WFO out of the hole. And if you do that too much you'll have a spun prop on either engine.
So, if you're still interested, there's nothing wrong with a Honda 135 on that boat.

This. There are well intentioned comments here, but many use the 115 and the weight is the same. It will work. I've seen a 22 with a 150 on it, and the owner told me that as long as he kept off the throttle it was no problem for the boat. While that's an anecdote, it's real world feedback.
The power ratings on these boats are a centerline, lowest common denominator, CYA, on-size fits all recommendation based on the idea that the operator can and will put the hammer down. It's not necessary to do that ever, and there are also times when extra power can save your bacon, like when you get out of position in a heavy following sea and need abundant power to keep a large wave from overtaking you.
I run boats with obscene power to weight ratios sometimes, with enough power to easily swamp, roll or sink themselves if operated improperly. But I'm alive and well because I don't operate them improperly.
Additionally, one can install governors to limit the amount of an engines power one has available to them, or could even detune the motor all the way down to 115hp without changing any major components (I know this to be true on slightly older Hondas, but not sure about your year, because you the OP didn't mention).
Now, this is not an ideal motor, but you are certainly on the correct side of needing to trade your motor out. A dealer likely won't be your best option, but craigslist might allow you to find someone with a 90, or a lighter 115, and trade you straight across for the larger engine.
I suppose the point I'm circling is that if this is the boat for you, I wouldn't necessarily let the extra power stop you from purchasing the boat. I'd be more concerned with the condition of the hull, if the core is intact, if the penetrations into the core are done properly and well sealed, if the equipment included is the specific equipment I want (this will save many boat bucks in the next couple years) and await an opportunity to repower with an engine you find ideal.
If you are able to reserve funds for a repower now and wait to recoup your costs after you sell your 135, an brand new honda 90 is a very nice motor (I just got one at work), or can negotiate the purchase of the boat without the engine you'd be all set. If not, you could purchase the while shebang, then remove the 135 and sell it, and afterwards find a newer used BF90, and you should be able to buy a newer one than you sell, or have some money leftover for bait and gas if you sell your 135 well.
I'd make sure the thing has trim tabs though, or you'll never have a decent ride through chop at any speed.
