I've had a 24volt 60 Inch shaft on my 21 foot Mako Center Console boat for several years. LOVE it! Customer service is the BOMB! They work with you...Walk you through whatever you may need. Get you parts in a day or 2! Has been a GAME Changer for me, fishing by myself in STRONG currents and Strong winds. Stays put four HOURS! Never ran out of battery either...I would HIGHLY recommend them! All sealed Solid state parts. Pretty easy to deploy.
