About Us

Lower Unit Parts Gear Sets


A little more information about us: We are Advanced Marine Inc located in northern Michigan in the town of Interlochen.

Advanced Marine has been servicing boaters since 1986 and although we no longer offer general repair, we still have a strong focus on lower units and we have very competitive pricing and quality.

We are committed to making your purchase a pleasant experience. Most of our customers that purchase lower units from us install the unit and adjust it themselves. We offer over the phone assistance with your home installation if needed. If you are after parts, we only sell trusted high quality lower unit replacement parts, the same parts we put into our units. You can buy here with confidence.

We have 5 employees working here, which makes us a small to medium-sized business. We like it that way so that we can make sure that our customers get the attention they deserve. It’s not unusual for me to be answering questions and helping customers from 9 in the morning till 8PM EST in the summer months. Feel free to call anytime you need a parts quote or some advice.
