3 Most Common Problems With Tahoe Boats:

1. Power Loss Issue:  

The first common issue that may arise with any Tahoe boat is the visible loss of engine power.  

Often consumers experience that while they are on the water to enjoy fishing adventures or a long round-up trip on weekends, the boat suddenly starts stuttering and eventually stops because of excessive power loss. 

But remember, it is one of the common technical problems with every boat or outboard and not a major issue if you know how to fix it.

Possible Fix 

First, you need to identify the core reason behind this sudden commotion to fix the problem.

It can happen if you ran out of fuel or have dirty or bad fuel…

First, check your gas or fuel tank whether you have enough gasoline in there or the fuel mixture has become dirty or bad. If your gas tank is nearly empty, refill your gas tank with fresh fuel. 

While winterizing your Tahoe boat, add a good amount of fuel stabilizer to ensure you run the boat long enough to receive the treated gasoline into the engine.

If you see that an excessive number of debris has ruined your fuel, fix the dirty fuel by following any of these mentioned steps:

Step :1 If you use ethanol-free gas, first, remove some portion of your existing old fuel and add a quality amount of fresh gasoline to it. Fresh gasoline is able to clean the bad ethanol-free gas. 

Note that Ethanol-free gas older than one year can cause severe damage to your boat’s engine. To prevent this, do not use regular fuel for more than one month and ethanol-free gas for more than six months.

Step:2 You can drain the fuel by using either an electric pump machine or a primer bulb. 

Firstly, connecting the electric pump or primer bulb with your boat’s pump outlet. If it is your first time take help from the given diagram in your boat’s service manual or hire a professional.

Remember, electric pump machines are best for cleaning large amounts of fuel, and for small quantity a primer bulb works perfectly.

Step:3 For small amount of fuel, you can also use the siphoning method. First, disconnect the hose from the primer bulb’s engine side and set containers under your fuel tank.  

Next, hook up a hose tube from the primer bulb’s engine side and run that through the garboard drain plug to all the way the boat’s external body. Now connect the hose tube’s other end in the gas container and process. 

But remember, the siphoning method only works better if you can easily reach the boat’s fuel tank with that hose tube.  

A damaged or faulty filter can also lead to such engine problems…

For a dirty or faulty filter, you can either drain out all the debris out from the filter or replace it with a new filter based on your boat’s service manual spec details.

For cleaning the filter, first, turn on your boat engine. When the engine gets warm enough to start, turn it off. Now remove the filter from the fuel line, and reverse the fuel filter by connecting the fuel pump side only. Now, bring a can or container and engage the starter to drain out the debris. 

Remember replacing the clogged, damaged, or faulty filter is the better and long-term solution.

2. Trouble In Starting Tahoe Boat’s Engine: 

This is another commonly mentioned problem that the majority of the Tahoe boat users have experienced till now. 

Based on several user’s opinions, sometimes the Tahoe boat delays or struggles when they try to start the engine. It must be overwhelming to experience, but technical issues like this can be easily fixable too. 

Let’s learn more about some of the possible reasons that can cause this and how to solve the problem with quick tricks. 

Possible Fix 

It can happen due to one of the following reasons, so investigate all possible faults thoroughly.

Possible culprit can be the kill switch, shifter, and even starter switch…

You can start by checking the kill switch condition. If the connection is loose or the switch is not securely connected, disconnect and remove it. Then, reinsert the kill switch in the place and secure all the connections accurately. If the kill switch is broken or cracked, replace it. 

Next, you need to make sure that the shifter switch is neutral. 

Remember sometimes, the dash-mounted ignition switch gets loose from its connection and allows the whole switch mechanism to turn with the ignition key. That is when the starter switch turns bad.

To fix this by checking behind the dash whether the retaining nut or mounting screws are loose, and tighten them properly.

Problem can arise because of low battery…

First, carefully observe whether the starter is making the usual groaning noise or not. If it is making the noise but still failing to engage, that means you have a low battery issue. 

In that case, disconnect all the connectors, screws, and bolts that hold the battery in place. Then, pull the battery out and check whether the battery or the connectors are covered with debris. If so, clean them and make sure to dry them off with a cotton towel. 

Next, charge the battery fully and re-insert it again. Make sure all the connections are secured and on point. If the battery is damaged, replace it. 

Also, if you do not have any secondary battery, do not drain your battery’s charge by constantly playing music or using other electronic devices.

Fouled or damaged plugs can be another possible reason…

If any fuel tank connecting plugs or spark plugs are damaged or loose, your boat engine may experience this issue. So, inspect those and replace the damaged parts or tighten the connection if required.

Check the spark plugs inside of the ignition system with a spark tester and if you cannot see the spark or weak spark, change the spark plugs.

Also, do not forget to thoroughly check all the nuts, bolts, and other connecting screws around the engine and fuel tank areas. Secure all the mounting connections as required.

3. Broken Or Cracked Drive Belt 

Often users experience that the broken or damaged drive belt forces the boat to shut down abruptly.

When the overheat warning light turns on or the voltmeter indicates that the alternator is not charging, that a clear sign of a broken drive belt issue. But it is a very common problem that mostly arises with the inboard motors.

Tahoe also has some boat models, which have inboards with outdrives. So, users should get a heads up on dealing with this problem beforehand.

Possible Fix 

Loose connection or rough spots on the pulleys may cause drive belt damage…

First, you need to inspect the condition of the drive belt. If the loose connection is the problem, tighten all the connectors securely and dress the drive belt. 

You should also check the condition of the pulleys because corrosion causes rough spots on the pulleys, which eventually damage or ruin the drive belt entirely. If corrosion is the main culprit, you need to clean up the entire pulleys passages. 

When your drive belt breaks, you can create an alternative drive belt by using a fishing line, pantyhose, or other similar pieces. 

But remember, it is a temporary solution and that alternative option will not last long. The best idea is to replace the broken drive belt with a new one.
