Sales people were very knowledgeable would recommend this company 100%
This kit solved my problem with a discontinued part in my Mercruiser stock ignition system, It was fairly simple to install and the instructions were fantastic. My boat never ran better! It's a perfect solution to solve your ignition issues. The sale rep and her dad's advice sealed the deal for me!
Quality of all the materials was excellent. Instructions were great made the upgrade go very smooth. Very happy with this upgrade.
very nice so far works great it replaced a mercury thunderbolt 5 system
Distributor was an easy install and worked perfect. I could not use the sparkplug wires because they were 90 degree boots on both ends. My 454 Crusaders use straight boots on the engine side.
The product fixed my problem. Problem was my boat wouldn't start due to a ignition module that was obsolete. So a friend mentioned to me about your product. It's installed works fine.
So far so good!! Install was relatively easy with the instructions. Fires up great and the engine almost sounds better. Great upgrade from my Mallory distributor system which was starting to give me constant ignition problems.
Yes it’s a bit pricey but the performance gaines will definitely shine. Our thunderbolt 5 has been acting up with run ability issues and this option is truly the best way to go.
Waiting to install parts when I launch my boat.
This kit has high quality components and great instructions.
Purrs like a kitten. Had a junkie pertronix product in there that filled on me twice. Mechanic suggested going to HEI system and it was the best move I ever did.
Just installed on my two Crusader model 350 engines. Came with a high recommendation from customer service, who were very helpful. I liked the feature of an electronic Delco module. Very good instructions and installation went smoothly. Initial performance has been excellent. Hoping and expecting long term performance and reliability will hold up.
High quality parts at a price well below other vendors.
Helpful knowledgeable staff. Thank you.
Tanner was a big help clarifying the installation instructions System works great
Made a world of difference in my boat. Arrived next day while boat was on the lake. Saved my vacation!
great system and reasonable
Works as described. Excellent technical support.
Bought 2. Your tech said he experienced an issue last week with the model and in the timing mode it shut motor down. Had to get one from o reilly. We had expenses and additional tech time we feel we should be remunerated for.
