"When I first put my motor in

"When I first put my motor in gear, after a few seconds, I hear and feel a clunk sound like the motor pops out of gear and back in again. after getting underway, it does not do this. I am thinking it is a clutch issue, any thoughts? Any help greatly appreciated."
 
Brian if your engine is the V-

Brian if your engine is the V-150XRI (EFI)I think I have a manual somewhere on that! let me know the serial and i'll do some digging up to see what i can find out for you.
 
There are three different gear

There are three different gearboxes for the model range subject to serial numbers. One type is a racheting gearbox which can over run the clutch at idle or deceleration some other types cannot rachet and are locked your serial number is vital to determine the type of unit you have.
 
"Thanks for replying all,

"Thanks for replying all,

The serial # is 0G275857

Thanks again."
 
"Your model has the racheting

"Your model has the racheting type gearbox with a sliding clutch which is an attribute to the forwards gear, and mounted within that is a spring guide block, some ball bearings and a spring, a cross pin and a retainer spring. if something has come adrift inside this setup it could be causing the sliding clutch to stick under low idle revs. but once you power on the centrifugal force makes it engage correctly. All this gear is on the prop shaft on the inner side, Check and drain your lower leg oil and check for any fragments or see if it has any silvery look to the oil this may indicate if any metal parts have disintegrated or broken."

"also look at this, Number 36

"also look at this, Number 36 is the forwards gear
37,38,39, 40 are the spring, bearings and guide and 41 is the sliding clutch. 42 and 43 are the retainer spring and cross pin.

"Brent, can you explain the pa

"Brent, can you explain the parts( part # s )on this set-up that would utilize centrifigal force to engage this clutch????Normally you would find weights / levers and springs on that type of set-up.Maybe centrifical force has nothing to do with engaging a clutch on an outboard????"
 
"Bob, centrifical force has no

"Bob, centrifical force has no role. The spring holds the shift dog against the shift rod. The shift cam controls the position of the shift rod(and therefore the dog). When you turn the shift cam into forward, the rod moves forward and the shift dog is pushed into the forward gear by the spring. The shift dog is splined to the propshaft, and the gears spin free."
 
"Brent,

Thanks for the info

"Brent,

Thanks for the info, I will let you know how I make out with this."
 
"To try and clarify what Alask

"To try and clarify what Alaska Bob has posted and so he stops badgering me, Delete any reference to "centrifigal Force" a bad choice of words on my behalf. Chris1956 has answererd what i was trying to explain. i was merely showing the workings of the gears and offering a suggestion as to what could have gone wrong inside. To give a suggestion that it could sticking inside the mechanism? and what is possibly making it do what it does? My suggestions are merely food for thought.
Ps: Alaska Bob are you the Chef or Brians brother the fisherman from Petersburg?"
