Scag welding so close?

Question

My scag broke off 1 inch from the base of the casing. I was told if I weld a new scag on so close to the casing, the heat will damage the gear oil and gears that operate the prop movement. Is this true and if so is removing the bottom casing my only option for repair work?

Answer 1

get it welded!

Answer 2

No!!!!!!  Welding your skeg is the best option.  In fact this is done all the time.   The gear case needs to have the gears, shafts, and even the oil in the case, which help to dissipate the heat and prevent the housing from warping.    The remaining part is usually ground down to an inch or so, anyway.  If you notice the "web" thickens as you get near the "bullet".   I've never had any problems with gears or shift operation after this was done.    Over the years I've had hundreds of skegs welded, but I depended on the professionalism of the shops.  Most of the shops I used also repaired props, so they understood Alum welding and marine issues.  If they didn't feel it could be done they would tell me.   I depended on their advise.  Early on they fabricated the "new" skeg them selves.  Now, they are readily available.  It's a matter of grinding the old (broken) skeg off and welding on the new blank.   I've had this done in Maryland and Florida, and a "distributor"  who would pick up the case, take it to N.J. to a shop they used, and then bring it back the next week.  So, contact someone in your area and ask where they have had this work done in the past.  

       It's over $1500 cheaper than replacing the lower case.

Answer 3

Who ever told you this is wrong.You can have a complete skeg welded on your lower unit and it will not hurt anything.I have been working in the marine industry for over 30 years and cannot count how many I have had repaired.Years ago when you wanted this done they had you completely take it apart before they would weld on a new skeg.Now all you have

to do is remove the lower unit, drain the gear oil and remove your prop.So don't worry and I hope this helps.

Answer 5

joist file the scag as best as you can to it's original shape
