Intex Mariner 3 Review and Specs

Intex Recreation Corp. is the maker of the Intex Mariner 3. For more than 40 years, this company has been making high-quality but very affordable inflatable boats, among other consumer products that it sells around the world.

Mariner 3 is designed to accommodate three people comfortably. It can be used for fishing or just leisure boating and relaxing on the water. Recreational fishers will love this boat because it has plenty of room for all your fishing gear and other supplies.

In this review, I will present the specifications, features, and what comes in a package of the Intex Mariner 3. For its price point, Mariner 3 offers the best value. If you have a limited budget but seeking a high-quality boat, you may want to consider this three-seater inflatable boat.

What Is the Intex Mariner 3?

The Intex Mariner 3 is an inflatable boat that you can use for boating, fishing, or just plain relaxing all day on the water. This boat is built with very tough materials, making it puncture-resistant, long-lasting, and reliably durable. It can support the weight of three average-sized adults as well.

Features & Materials Used

Its hull is made of three super-tough layers of quality materials. There are two layers of heavy gauge PVC that are laminated to another layer of polyester mesh for extra reinforcement. Additional strength is provided by its heavy-duty flooring and keel rock guard. These features enhance the rigidity and stability of the boat.

This boat is equipped with two Boston valves attached to the main hull chamber. Also, the boat comes with a high-output hand pump. Inflating and deflating the boat is easy and fast when this hand pump is attached to the Boston valves.

No amount of air will escape while inflating this boat because the Boston valves are actually “check valves.” Additionally, the hand pump will pump air into the chambers, whether pulled in or pulled out. This combination results in much faster inflation and deflation of the boat.

Boat Accessories

The Intex Mariner 3 is also suitable for weekend boaters who don’t want to exert much effort in rowing and paddling. This boat comes with a mounting kit at the stern, and this platform will allow you to attach an outboard or trolling motor. With outboard power, you can go anywhere you want and won’t break a sweat.

The Intex Mariner 3 is supplied with many useful accessories. These accessories include two aluminum oars, grab handles on both ends, and all-around grab lines. It also includes other helpful accessories, such as two built-in fishing rod holders, oar holders, rotational oar locks, and many more. This boat comes with a U.S. Coast Guard ID, which means that it’s really safe to use on the water.

Video Reviews of the Intex Mariner 3

First Video Review

Crab Master did the first video review. The review starts with the boat not yet inflated and lying flat on the ground of a marina. He first pumped in some air (just enough to get it started) on both sides or hulls of the boat using the supplied hand pump.

Boat Assembly

Next, he inserted the floor of the boat and covered it with a black mat. He then resumed the pumping of air into the boat. The reviewer used a combination of a small electric air pump and the supplied hand pump until the boat was fully inflated.

He then attached the motor mounting fittings at the back of the boat. Then, he added the two seats made of plywood on the top of the boat crosswise. The seats, which he described as uncomfortable, rested on the top of the hulls. He tied it around the cleats of the boat with some black ropes to secure them.

The reviewer then carried the boat to the water and mounted the outboard motor. Then, he installed the propeller on the motor and connected the motor to the battery. He then untied the boat from its moors on the dock so that he can take the boat out to sea.

Testing the Boat on the Water

While on the water, he says he needs cup holders as there is none on the boat. The boat seems steady as the trolling motor on the water powers it. He took the boat out of the marina and into the bay. The boat is steady and solid at this kind of speed. He mentioned that the motor is already at its top speed. The reviewer steered the boat out into the sea but still close to the marina and then went back to the docks safely.

Second Video Review

Jiggy’s Outdoors made this second video review. In this video, the reviewer is comparing the Intex Mariner 3 with the Intex Mariner 4. He placed the boat side by side, maybe to make it easier for us to see their differences. The reviewer said he wanted something that he can pack and a boat that does not need a trailer.

Length and Width Comparison

As you can see in the video, Mariner 4 is definitely bigger than Mariner 3 (not much on the length but more on the width or beam of the boat). Mariner 4, he says, is probably only 10 inches to 12 inches longer and about 12 inches wider than Mariner 3.

Then, he put the two boats on top of each other to compare the length and width of Mariner 4 and Mariner 3. He observed that there is not much of a difference between these two inflatable boats.

What he liked about Mariner 3, though, is that it takes a shorter time to fill up compared to the slightly bigger Mariner 4. But for safety features, Mariner 4 is better because he said it has five air chambers instead of just 3 in the Mariner 3.
