Just purchased a 2008 ls 210 Crownline with 5.0L Merc and Alpha2.Trying to add trim tabs,the swim platform and the uneven transom has me a little concerned.Is it just a matter of trying to find any unit which will clear obstructions while ofc trying to stay on outter edge of waterline ? Has anyone put tabs on this model boat,I have not put boat in the water yet since I bought it.I'm doing this job for my brother in law who is the true owner of the boat,I'm just the mechanic thru marriage,to my sister ! Thanks for any suggestions.
