Honda 225 ex Race engine solid top mountings

[redthunder]

I have been offered an ex race 225 Honda 2008 that has solid top mountings. Will this harm my boat in any way or put extra stress on the transom?

Might help us, help you, if you tell us what Boat/Rib it's going on?

But I'm assuming you mean solid vers rubber mountings?

[outboardtech]

these engine's have been worked hard . I fthese are the engine's that the P1 BOY'S use then I would make sure all compressions are too spec with throttle valve closed and at wide open throttle . Check the OIL for no mulsified oil . Is this an engine from the boy's @ solent honda ??

Yes solid rather than rubber. It would be going on a ribcraft 6.8

I would think it would mean more vibration passing through the hull and yes it would put more stress on the transom, probably worth checking with RibCraft.

RIBcraft are the people you want to contact. A previous MD I worked for used to race in the Honda 4 stroke series, both in 150 and 225 classes. I can tell you that on these boats there are all sort of stress marks around the transom area's, but I would guess these boats are designed for a really hard life.

I can tell you however that whilst these engines do have a hard life when racing, they will have little hours on. As I was led to believe, they are all fully serviced with gearbox refills between race meets too all by the main dealer.

What's the history of the engine?

Is there any warranty left?

And probably a short one at that.

Compare to a drag racer - ooooodles of HP from a disproportionately small and highly supercharged engine - which is fine for the racing as long as it survives the 1/4 mile blast 'coz you can rebuild it between races. Phrases involving chocolate teapots come to mind if you want to drive dowm the M1 as it will have exploded by the time you get off the slip road! (extreme example used!)


Jumping back to this Yam, assuming the engine's OK internally, surely it's not a difficult job to replace the solid mounts with the standard ones?

possible power head off for the honda
