    Well first, don’t reuse that housing.  It will not clamp down properly with the plastic cracked like that.   $149??  No, that is not right.  $22.40 from marineengine.com

    Finally, do not use thread lock on those screws.  60-84 inch pounds is plenty to clamp/hold the bolts in place.  Coat the threads and shanks of the bolts libearlly with marine grease to help avoid this problem in the future and to make sure you will be able to get those bolts out in the future without using the torch and melting all the plastic!
