    So far I've had a terrible experience dealing with this company. I've placed two orders for a…read moremarine diagnostic unit and both, they canceled on me. They stated it was because i was having it shipped somewhere other than my billing address, which can't be that uncommon. And i get that is a common fraud flag. However, I provided a copy of my ID (drivers license) and attempted to pay a different way and was still not fulfilled.

    In response to your dissertation, Loren H., apparently you did not reply with all of your facts…read more First, have you seen your ratings on Yelp? Your bad reviews equal your good reviews. That alone tells the public something. It appears that positive reviews are being posted to counter the real negative experiences customers have had. That's how it looks from the outside. Let's go back to the beginning. In the spring of 2021 I first inquired about a 302 long block. I was told I would be placed on a waiting list because you had to find a 302 block and none were in stock. Two months later I called to check on the status and was told you were still waiting for a block. About another month later I called again and was told the order had been lost and that we would have to submit another one. At that point we were already past half of the fishing season here in New Jersey. Salt water season. I decided to pass because the delay had already left a bad taste. Spring of 2022 I placed the order again. Once again I was told I had to wait for a block to become available. That raised a question for me. Do you not specialize in 302 engines? These engines were widely used in boats in the 1970s and some into the 1980s. They are not exactly rare in the marine world. So it makes me wonder how your machine shop treats these older engines when they come through. What level of care and attention is actually given to them? About a month and a half later I called again and was told the engine was being built. Great. Eventually I received the engine. If you actually looked at your notes referenced in your dissertation, you would see that when I installed the engine everything on that boat was brand new. The stern drive water pickup pump was new. The circulating pump on the engine was new. The fuel pump was new. Intake manifold new. Risers and exhaust elbows new. Water hoses new. Everything was new. On the first startup the engine was completely out of balance. I spoke with Zach about it. We did not discuss timing at first. We discussed the possibility that the flywheel did not match the crankshaft. We went through all the possible causes of an imbalance. I made it clear that I am more than capable in my field of mechanics. It turned out the flywheel was the wrong one. That was an easy fix for me. I have owned this boat for 30 years. I have rebuilt it once before. New transom, completely rebuilt and overbuilt engine compartment, new fuel tank, new console, new T-top, and the entire boat rewired. I know this boat inside and out and could take it apart and put it back together blindfolded. The engine break-in went fine that fall. I ran two or three short days on the water, probably around 15 hours total. In the 2023 season I was able to run the boat five or six times. My fishing is primarily in the fall for striped bass. I run a landscape maintenance business, so early season boating is not something I have much time for. In 2024, on the second day out, I finally felt confident enough to run offshore about 25 miles to the Monster Ledge for mahi and tuna. Just after breaking out of the inlet the exhaust blew out on one side. With new risers and pumps installed, the question immediately became why it was running so hot. I checked the water flow, confirmed the risers were clear, and verified water was flowing properly. I replaced the hose and continued, but I constantly had to watch that side of the engine. I ran the boat maybe five or six times that season, but at that point I did not feel confident in the engine at all. For a $3,300 rebuild from a national company, it should have been reliable. In 2025 I ran the boat four times. By then the engine was running very rough. Oil smoke was coming out of the valve covers and oil was all over the engine compartment, which by the way had just been freshly painted. At that point I performed a compression test. You have those results. The spark plugs appear corroded because the boat operates in a saltwater environment. The ignition system is not old. It has a brand new Mallory Unilite distributor, new wires, and the plugs were new at the time of installation. Another issue I never mentioned before: the engine would not exceed 3300 RPM. It should peak closer to 4000 RPM. The tachometer is brand new as well, and the boat has completely new wiring throughout. My conclusion is that this engine was pushed through your shop so you could move on to engines you actually care about rebuilding. Based on the wet and dry compression results, it appears the valve job was incorrect and the valves were not seating properly. That would also explain the overheating issues. As for response time, it took more than two months for anyone to contact me. I finally received a call on the 29th. I believe it was the day after Christmas. I was honestly surprised to even receive a call at that point. I was told that from November until that date the paperwork had just reached someone's desk. More to say not enough room.
