Outboards on my signature 29

outboards

New member
This is my first post on here, all the way from Auckland New Zealand. I thought you may be interested in my 2006 Signature which has had a pair of 250hp Evinrude ETEC gen 2s strapped to its stern. Photos show it moored in the river behind my farm, the motors, getting a waterblast before putting it in my barn for winter and dash showing 48 knots, at which time she starts getting a bit hairy. Very few Chaparrals in NZ.

Nice. And your boating season is just starting isn't it? How long is your boating season?
So many are going to outboards instead of inboard outboard engines. Some with 4 or 5 outboards. Shocking to this old boater.
 
Starting to warm up a little. Day temps around 65 so nearly time to apply the antifoul and relaunch the boat.Temp will slowly creep up to around 80 in Jan/Feb and we will leave boat in water until May so I guess we get 7 or 8 months of reasonable weather.We only get down to 32f for a few mornings and the frost is always gone by 8am

I have considered doing the same for my 1992 Signature 28. It has been in three different shops in the last four years trying to isolate a transom leak around the starboard VP sterndrive(caused by the first shop fixing a raw water leak). It is probably due for a repower as the 4.3L engines show 600+ hrs each. The benefits are numerous including easier winterizing/maintenance and gaining hold space where the engines now reside. My concerns were primarily related to moving the center of gravity that far back. Did you add some ballast forward(it appears to float very flat)? Another concern is providing appropriate structure to the swim deck. If you could PM me or respond here with more details, I would very much appreciate it. Our boating season starts in April at Lake Powell, and I would like to have enough information to move forward with current repair or outboard repower before the new year.
 
I have no forward ballast and as you can see the boat sits perfectly.The engines are 2strokes and I believe alot lighter than 4 strokes.I never drove the boat with the original inboards and therefore can not help with ride angle etc.I almost never need to use the trim tabs unless I am cruising under maybe 20mph with full fuel and say 6 persons seated outside.With 10 adults sitting out side,as you would expect it points skyward for a few seconds and likes a little trim to keep the bow down.The no 1 reason I bought this particular boat was because of the outboard conversion and 100/cent happy with it.The mounting pod was manufactured locally.I will take a touch tomorrow and see if I can get detailed photos of the construction and post here in a few days time
 
Thank you, I'm a Mechanical Engineer and could probably figure out an appropriate setup, but having a working example for reference would be very helpful. Thanks again.
