Ironically, it wasn't until the mid 70's that the blisters started showing
up on recreational boats. My father-in-law's was a '72 and was a
recreational version of one of the Vietnam era patrol gunboats (except the
military ones had jet drives instead of props). The fiberglass was rough
due to minimal upkeep, but there were no blisters.

The Uniflite Mega that I had was a '78 or '79. (I forget which) It had
blisters on the topsides, but none that we ever noticed below the
waterline.

Best current theories about the mid-70s blister epidemic are that the
resin vendors changed their product formulation due to high petro
prices or that builders changed their wet out/gel coat procedures,
probably the former.

The change in resin theory is the one I believe is true. It also killed
Uniflite unfortunately.

The blisters came with the switch in the fire retardant chemical used
in the resin formulation. Uniflites from 75 on have the problem. The
blisters result from a chemical reaction brought on from exposure to
heat- so the problem is much worse in southern Uniflites. Many
Uniflites are used in Alaska, and apparently the problem is unknown
there. The blisters are a cosmetic issue, and cause no structural
harm. Mine are fairly minimal, and none below the waterline.
Ironically, what finally did in Uniflite was a fire at their main
plant in Bellingham, Washington. The boats were fire retardant, but
the factory wasn't...

Anyway, does anyone have any more advice about setting up the shift/
throttle controls on a twin inboard? What's your preferred setup?
