I found that boatplicity had the best price I could find on the Scotty rod holders and mounts that I needed. I had never ordered from or heard of them before. But I took a chance and placed an order with them anyway because of the lowest price. I was pleasantly surprised! Everything went GREAT!!! I would buy from them again!!! (I do think I should have gotten free shipping on an order that was over $100.00 but I did not.)

FAST DELIVERY. NO ISSUES AT ALL. Would highly recommend

great fast easy to navigate cheap 2 day shipping

Had the part

Happy face

I found the engine mounts I needed but THM did not carry the transmission mounts I needed from the same manufacturer. I had to go directly to the manufacturer website (Innovative) to find them. THM had the best price on the engine mounts though.
