Honda 90 upgrade to 135

[Bigmuz7]

Guys,.. thinking of upgrading my 08 Honda 90 to a 135. My Valiant has big toobs, with plenty length aft, so weight not a problem, power limit is 135 too so no probs there,... just feel I need a bit of extra go, hull is very stable so I think she could handle it no probs ,.. question is, will it slot onto the same place on the transom ?, are the saddles the same on the 90 and 135 ?, and I assume all my existing steering and wiring would change over too ? Any Honda dealers out there ?

No experience of Hondas, but the majority of engines are very easy to swap over. Just unplug/disconnect everything, bolt the new engine on and hook it all back up. Only major thing I can think of is steering - make sure it's rated for the new engine. When I changed my 140 to a 225 it was dead easy - fortunately the boat was built with 300hp steering so it was literally just a case of plugging the new engine in.

I just swapped a Yam for a Merc, and apart form some minor adjustments to the remotes loom (i.e replacing the spade connectors on the ASIG switch connections to bullets) and swapping the thrtotttle / gear connectors on the engine end of the cables form Yam to Merc style, it was pretty much plug'n'play. I now have a Merc engine, Yam remotes / switches & Suzuki instrumentation.

Or, in short sticking with the same manufacturer should be a relatively easy swap, assuming no massive technology jumps (e.g. mechanical to electronic throttle or going from manual to power trim), in which case you may need to start a major rewiring.
