First off, kudos on maintaining your 1988 Parker 23SE since new and adapting it to a dual console setup – it looks fantastic!
Now, regarding trim tabs, you might be missing out on several advantages. Trim tabs can significantly enhance the performance and overall boating experience, especially on a boat with multiple engine changes. Here's what you could gain:
- Improved Stability and Ride Comfort: Trim tabs provide better stability, reducing the boat's tendency to rock and roll. This is particularly beneficial in varying sea conditions, offering a smoother and more comfortable ride.
- Enhanced Fuel Efficiency: By adjusting the trim of your boat, trim tabs can optimize its running angle, leading to improved fuel efficiency. This can be especially noticeable during cruising and long journeys.
- Better Control in Challenging Conditions: Trim tabs allow you to adjust the boat's attitude, providing better control in challenging situations like heavy seas or strong currents. This is crucial for maintaining a safe and predictable ride.
- Optimal Planning: Trim tabs help the boat plane more efficiently, reducing time to plane and improving overall planning performance. This is particularly advantageous when dealing with different engine setups.
Now, regarding the size recommendation, it's wise to consider both the manufacturer's suggestion and Bennett's recommendation. While Parker may recommend 12 x 12, Bennett's suggestion of 24 x 9 could potentially offer more surface area, providing greater control and stability.
However, it's crucial to strike a balance. Too large trim tabs can create excess drag and potentially lead to some of the issues mentioned in the previous response. I'd recommend consulting with a marine professional or contacting Bennett directly to discuss your specific setup and get their expert opinion.
