Starting Battery vs. House Battery

I''ve done a bit of research and am still a bit confused on this.

My plan is to have a 3 battery system in my new to me Pearson Wanderer. It will consist of 2 banks, the first being a single battery for the motor, and a two battery bank (house batteries) for all other electronics.

The house batteries will be deep cycle batteries. The question revolves around the selection of the motor battery. From my research, I''m better off having 3 identical batteries (from a charging aspect), but for a starting aspect, I don''t want this to be a deep cycle battery (or am I wrong)?

Basically, is there a problem using a deep cycle battery as a starter battery for the motor? If it matters, the motor is a 25 hp Universal diesal.

The electrical system on this boat is a nightmare and I''m basically going to gut it and start over, but want to get it right the first time.

I''m currently working my way through Nigel''s book on electrical systems, but have this one question (for now).
