clunking sound

[Kajun37]

1990 120 force...i hearing a clunking sound when i go from a dead stop to WOT to get up on plane....motor kinda shakes...does it about 2 or 3 times.. then once i get up on plane it doesnt do it anymore...if i ease unto plane very slowly most time it wont do it.<br /><br />i do have a broken front lower mount..i'm hoping that is the problem instead of my lower unit....any ideas?

Re: clunking sound

my 150 had same issue found out it was forward gear and clutch dog ears rounded slightly causing them to slip had them machined and fixed prob. new gear and dog lots of $$. will have to dissasemble to get forward gear out. but first i just flipped clutch dog around and tried it fixed for awhile then were gear was worn just wore clutch dog again. was told was caused by misadjusted carbs and slowly engaging to forward gear.
