I just turned a 4hp johnson into a 6.5hp Briggs, Now I'm like you I'm going for a 13hp on an old 7.5hp outboard lower unit. How's yours coming, been 3 months.

doing great, at newyears eve we selebrated on board and have some fun. now i am thinking to make something with an inboard engine.

[withoutanoutboard1]

does the briggs and stratton idle slow enough to use the forward ,neutral and reverse?

[markskemotor]

yes, it works perfectly, only on full trottle the engine has no power left, maby i replace it by a 14 hp vanguard v twin so i have a little extra power left.

Nice job. Is that a centrifual clutch below the engine?

[markskemotor]

No, its an extra steel flywheel i use to connect the drive shaft of the engine to the axle of the propeller

You told this is an old Envrude tail? What was the power of the original two stroke engine? What is the model, weight and lenght of this boat ? Fiberglass or aluminum?

Greetings from Brazil.

[markskemotor]

yes, This is an old evenrude tail with forward and reverse. get rid of the damn two stroke and build an 8 hp briggs on it, next month i am going to replace it by an 14hp vanguard V2. The 8 hp does it good but he has no reserve left, so it is going to be better fore the engine if it is a 14hp.

So, to be continued.

The first try was an 4hp lawn mower engine, but he could not handle the power.
